10 * POWER7 optimizations: memset
14 * The following bugs are resolved with this release:
16 3662, 4457, 5553, 10162, 10401, 10414, 10554, 10824, 10864, 10915, 10918,
17 10936, 10939, 10958, 10968, 10969, 10972, 10992, 11000, 11001, 11007,
18 11010, 11027, 11039, 11040, 11041, 11043, 11046, 11056, 11070, 11093,
19 11115, 11120, 11125, 11126, 11127, 11134, 11141, 11149, 11183, 11184,
20 11185, 11186, 11187, 11188, 11189, 11190, 11191, 11192, 11193, 11194,
21 11200, 11230, 11235, 11242, 11254, 11258, 11271, 11272, 11276, 11279,

31 * The dynamic linker now recognizes supported ABI versions from the
32 EI_ABIVERSION field in the ELF header.
33 Implemented by Ulrich Drepper.
35 * New NIS mode selector ADJUNCT_AS_SHADOW. The passwd.adjunct.byname table
36 will not be used to fill in password fields in the passwd.byname replies.
37 Instead it is used to synthesize the shadow.byname table, should it be
38 missing. This is a useful mode in some installations involving Solaris.
39 Implemented by Ulrich Drepper.
41 * New locales: kok_IN, sq_MK, cv_RU

54 * New interfaces: execvpe, pthread_sigqueue, mkstemps, mkstemps64, mkostemps,
56 Implemented by Ulrich Drepper.
58 * Checking version of longjmp added that fails if an uninitialized stack
59 frame would be created. Implemented by Ulrich Drepper.
61 * STT_GNU_IFUNC is now supported in static executables.
62 Implemented by H.J. Lu.
64 * STT_GNU_IFUNC implemented for PPC by Alan Modra.
66 * New optimized string functions for x86-64: strstr, strcasestr, memcmp,
67 strcspn, strpbrk, strspn, strcpy, stpcpy, strncpy, strcmp (SSE2, SSE4.2),
68 strncmp (SSE2, SSE4.2), strchr (SSE4.2), strrchr (SSE4.2).
69 Contributed by H.J. Lu.
71 strlen, rawmemchr, strcmp (SSSE3), strncmp (SSSE3).
72 Implemented by Ulrich Drepper.
74 * New optimized string functions for x86: strlen, strcspn, strspn, strpbrk,

82 Implemented by H.J. Lu.
84 * STB_GNU_UNIQUE support added.
85 Implemented by Ulrich Drepper.
87 * Implement second fallback mode for optimized DNS lookup for even more
88 broken environments. If two requests from the same port are not
89 handled correctly close the socket and open a new one before sending
90 the second request. The 'single-request-reopen' option in /etc/resolv.conf
91 can be used to select this mode right away, instead of rediscovering the
92 necessity is every process again.
93 Implemented by Ulrich Drepper.
95 * New resolver flag RES_USE_DNSSEC to enable use of verified lookup.
96 Implemented by Adam Tkac.
98 * Optimized iconv conversions for S390x.

124 could lead to compile errors for invalid C++ code.
126 * XPG7/POSIX 2008 compilation environment. Many GNU-specific functions are
129 * New POSIX 2008 interface: psiginfo
130 Implemented by Ulrich Drepper.
132 * New ISO C++1x interfaces: quick_exit, at_quick_exit
133 Implemented by Ulrich Drepper.
135 * Support for selecting between multiple function definitions at runtime
136 using STT_GNU_IFUNC symbols. Implemented by Ulrich Drepper.
138 * The libcrypt library can now use the hash function implementations in
139 NSS. Implemented by Ulrich Drepper.
141 * The malloc implementation can be compiled to be less memory efficient
142 but higher performing in multi-threaded programs.
143 Implemented by Ulrich Drepper.
145 * New locales: nan_TW@latin, ks_IN
147 * Faster strlen, strchr, strchrnul, strrchr, memchr, and rawmemchr for x86-64.
148 Implemented by Ulrich Drepper.
150 * Extended printf hook support. It is possible to use user-defined types
151 and extend existing format specifiers.
152 Implemented by Ulrich Drepper.
154 * Handling for group shadow files has been added.
155 Implemented by Ulrich Drepper.
157 * DNS IPv4-IPv6 parallel lookup now deals better with broken DNS
158 servers (the case, e.g., for some people using the built-in DNS
159 server in ADSL modems/routers). There is a once-per-process timeout
160 in case of a broken server. To avoid it, users can run nscd or put
161 'options single-request' in /etc/resolv.conf.
162 Implemented by Ulrich Drepper.
166 * The following bugs are resolved with this release:
168 3406, 5209, 5210, 5381, 5794, 5814, 5911, 6428, 6438, 6442, 6447, 6461,

187 * New implementation of memmem, strstr, and strcasestr which is O(n).
188 Implemented by Eric Blake.
190 * New Linux interfaces: inotify_init1, dup3, epoll_create1, pipe2
192 * Implement "e" option for popen to open file descriptor with the
193 close-on-exec flag set. Implemented by Ulrich Drepper.
195 * Implement "b" mode for fmemopen. In this mode writes writes don't
196 implicitly add a NUL byte and seeks from the end of the buffer really
197 use the buffer end, not the string length as the basis.
198 Implemented by Ulrich Drepper.
200 * Many functions, exported and internal, now atomically set the close-on-exec
201 flag when run on a sufficiently new kernel. Implemented by Ulrich Drepper.
203 * Sorting rules for some Indian languages (Kannada, Gurumukhi, Telugu,
205 Implemented by Pravin Satpute.

237 vdprintf, and obstack_vprintf.
238 Implemented by Jakub Jelinek.
240 * Faster memset for x86-64.
241 Implemented by Harsha Jagasia and H.J. Lu.
243 * Faster memcpy on x86.
244 Implemented by Ulrich Drepper.
246 * ARG_MAX is not anymore constant on Linux. Use sysconf(_SC_ARG_MAX).

331 3225, 3251, 3252, 3253, 3273
333 * For Linux, the sorting of addresses returned by getaddrinfo now also
334 handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled.
335 Implemented by Ulrich Drepper.
337 * Allow system admin to configure getaddrinfo with the /etc/gai.conf file.
338 Implemented by Ulrich Drepper.
340 * New Linux interfaces: splice, tee, sync_file_range, vmsplice.
342 * New iconv module for MIK. Contributed by Alexander Shopov.
344 * For sites with broken group and/or passwd database, the auto-propagate
345 option of nscd can prevent creating ID lookup entries from the results
346 of a name lookup and vice versa. This usually is no problem but some
347 site might have problems with the default behavior.
348 Implemented by Ulrich Drepper.
350 * Iterating over entire database in NIS can be slow. With the
351 SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
352 to trade time for memory. The entire database will be read at once.
353 Implemented by Ulrich Drepper.
355 * The interfaces introduced in RFC 3542 have been implemented by
358 * Support for the new ELF hash table format was added by Ulrich Drepper.
360 * Support for priority inheritance mutexes added by Jakub Jelinek and
363 * Support for priority protected mutexes added by Jakub Jelinek.
365 * New locales: nr_ZA, pa_PK, ca_AD, ca_FR, ca_IT, el_CY, tr_CY, as_IN,
366 or_IN, csb_PL, fy_NL, sr_ME.
370 * More overflow detection functions.
372 * New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153,
373 IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba.

379 IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed
380 by Masahide Washizawa.
382 * It is now possible to install audit libraries for the dynamic linker using
383 LD_AUDIT. Implemented by Ulrich Drepper.
385 * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
386 longer supported. The new NPTL implementation requires Linux 2.6 kernels.
387 For a libc and libpthread that works well on Linux 2.4 kernels, we
388 recommend using the stable 2.3 branch.
390 * The new function open_wmemstream acts like open_memstream,
391 but uses a wchar_t wide character buffer.
393 * The new function ppoll is an improved version of poll, similar to pselect.
395 * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
396 futimesat, faccessat, mkdirat, mkfifoat, mknodat,
397 renameat, unlinkat, linkat, symlinkat, readlinkat.
399 * New Linux kernel system calls: unshare,
400 inotify_init, inotify_add_watch, inotify_rm_watch.
402 * The euidaccess function is now also known by the alias eaccess,
403 for compatibility with some other systems.
405 * Timezone data updated to 2006b version.
409 * The following bugs are resolved with this release:

420 * As of this release, GCC 4 can be used to compile the C Library.
422 * Timezone data updated to 2005m version.
426 * The following bugs are resolved with this release:
428 284, 592, 602, 626, 633, 640, 650, 661, 671, 681, 693, 700, 710, 719,

433 Visit <http://sources.redhat.com/bugzilla/> for the details of each bug.
437 * Support for RFC 3678. Real implementations exist only for Linux so far.
438 Implemented by Ulrich Drepper.
440 * nscd can now cache entries persistently. Expiring entries are reloaded.
441 For speedups the cache can be shared in memory with client processes.
442 Implemented by Ulrich Drepper.
444 * nscd can now perform SELinux checks.
445 Implemented by Matthew Rickard <mjricka@epoch.ncsc.mil>.
447 * getaddrinfo queries are now cached. Canonical name lookup is performed
449 Implemented by Ulrich Drepper.
451 * The nothrow function attribute is used when headers are used by gcc when
452 compiling C code. This can avoid significant amounts of exception
455 * The malloc functions perform more error checking and are stricter when
456 it comes to reacting on errors. The default action is to terminate
457 the process after showing an error message. Implemented by Ulrich Drepper.
459 * Reverse lookups of IPv6 addresses does not use bit string or .ip6.int
460 lookups anymore unless explicitly requested. Implemented by Ulrich Drepper.
462 * Namespaces in ld.so are implemented. DSOs can be loaded in separate
463 namespaces using the new function dlmopen(). This feature is of course,
464 like most other dynamic loading functionality, not available in statically
465 linked applications. Implemented by Ulrich Drepper.
467 * Low-overhead boundary checking variants of string and some stdio functions
468 were added. These are to be used in conjunction with a gcc patch by
469 Jakub Jelinek which adds calls to these functions if possible.
470 Implemented by Jakub Jelinek and Ulrich Drepper.
472 * Old code for several operating systems and machine architectures that
473 have not been in working condition in a long time have been removed from
474 the main source tree maintained by the GNU C Library's maintainers.
475 These files are now reside in the separate `ports' source module
476 that is usable as an add-on when building the library.
480 * New functions `dladdr1' and `dlinfo' in <dlfcn.h> provide more ways to
481 interrogate the dynamic linker, compatible with the Solaris interface.
483 * ELF thread-local storage support (TLS) now works on PowerPC and PowerPC64;
484 implemented by Paul Mackerras, Steven Munroe, and Roland McGrath.
486 * getifaddrs now uses the netlink interface on Linux to get its information.
487 Implemented by Thorsten Kukuk.
489 * getaddrinfo now implements AI_V4MAPPED, AI_ALL, and AI_ADDRCONF.
490 Implemented by Ulrich Drepper.
492 * support for non-executable stacks on x86 has been added. Changes mostly
495 * regex is now much faster for multibyte locales. Changes by Jakub Jelinek
498 * getaddrinfo now performs destination address selection according to
503 * Thread-safe interfaces for many functions that access locale data
504 were added in version 2.3, but these features were omitted from NEWS.
505 Many functions have variants with an `_l' suffix that take a `locale_t'
506 object as a parameter rather than consulting the current locale.
507 The new functions `newlocale', `duplocale', and `freelocale' in <locale.h>
508 create and maintain `locale_t' objects. Additionally, the new function
509 `uselocale' sets "the current locale" (as used by functions not so
510 parameterized) set for an individual thread. These features were added
511 in version 2.3, implemented by Ulrich Drepper and Roland McGrath.
513 * The functions getresuid, getresgid, setresuid, and setresgid, which
514 have long been available on Linux, are now declared in <unistd.h>
515 and are now also available on the Hurd.
517 * ELF thread-local storage support (TLS) now works on x86-64.
519 * The new dynamic string token $LIB is expanded in shared library names.
520 This normally expands to lib, but on some 64-bit platforms to lib64 instead.
522 * Aldy Hernandez contributed complete software floating point support for
523 PowerPC machines with no FPU.
525 * fexecve is implemented on Linux.
527 * The `btowc' function should work at least twice as fast due to
528 specialized callbacks in the iconv modules. Implemented by Bruno Haible.
530 * With approriate thread add-ons cancelable functions are now implemented
531 in libc.so as well. No need to call the function in libpthread. This
532 change allowed to finally disable the incorrect and expensive handling
533 of weak definition in ld.so.
535 * Yet more PLT entries in libc.so have been removed. We finally arrived
536 at the bare minimum. Startup times improved appropriately.
538 * Support for the new Linux/x86 system call interface was added. The
539 AT_SYSINFO auxiliary vector entry is recognized and handled.
543 * Masahide Washizawa contributed iconv modules for IBM1163 and IBM1164
546 * iconv (the program and the interface) now accepts empty names (excluding
547 options like //TRANSLIT) to mean "use charset of current locale".
549 * localedef can now transliterate characters in strings which are not in
550 the provided charmap. The information from the input locale is used.
552 * Prelinking support was added for ELF targets. This requires additional
553 tools and recent versions of the GNU binutils. Contributed by Jakub Jelinek.
555 * Read-only stdio streams now use mmap to speed up operation by eliminating
556 copying and buffer underflows. To use add 'm' to the mode string of
557 the fopen/fdopen/freopen call. Implemented by Ulrich Drepper.
559 * The malloc functions were completely rewritten by Wolfram Gloger based
560 on Doug Lea's malloc-2.7.0.c.
562 * Isamu Hasegawa contributed a completely new and POSIX-conformant
563 implementation of regex.
565 * Bruno Haible upgraded the iconv and locale implementation to support
568 * Contents of the LC_* and LANG environment variables in the CEN style are
569 not recognized anymore. It never was used. Change by Ulrich Drepper.
571 * The runtime (ld.so, libc, libpthread for Linux) now can handle the ELF
572 thread-local storage (TLS) ABI on some platforms.
573 Changes by Ulrich Drepper. SH support by Kaz Kojima.
575 * Bruno Haible contributed iconv converters for ISO-2022-JP-3, SHIFT JIS-X0213,
576 EUC-JISX0213, and TSCII.
578 * New header <ifaddrs.h> with functions `getifaddrs' and `freeifaddrs':
579 BSD-compatible interface for getting all network interface addresses.
580 Implementation for IPv4 by Roland McGrath.
582 * Loading of locale data is faster due to the introduction of a locale
583 archive. Implemented by Roland McGrath and Ulrich Drepper.
585 * Startup times are significantly reduced by not using exported functions
586 inside the library itself. Changes by Jakub Jelinek, Roland McGrath,
589 * Steven Munroe contributed a port to PowerPC64/Linux.
593 * The Hurd now uses the GNU libio implementation of stdio rather than the
594 old GNU stdio implementation, and uses a new ABI (libc.so.0.3).
596 * The Hurd on x86 now has the `ioperm' function and <sys/io.h> header file
597 with the same behavior as the Linux system call of the same name.
601 * Stephen Moshier implemented log2, log10, powl and cbrtl for the
602 128-bit long double format.
604 * Masahide Washizawa contributed iconv modules for IBM1132, IBM1133, IBM1160,
605 IBM1161, and IBM1162 charsets.
607 * Andreas Jaeger contributed a port to x86-64/Linux.
609 * Peter Bruin contributed a port to PowerPC/Hurd.
611 * libc functions using I/O streams now can handle wide-oriented streams
614 * optimizations in the dynamic linker. Binaries created by recent binutils
615 versions start up quicker due to reduced time spent on relocations.
617 * Support for use of gcc3 added by Jakub Jelinek and HJ Lu.
621 * Stephen Moshier implemented cosh, expm1, log1p, acos, sinh, tanh,
622 asinh, atanh, j0 for the 128-bit long double format.
624 * Bruno Haible updated all the code handling Unicode in some form to
627 * Speed of regex for single-byte locales is back to previous levels.
628 Patch by Isamu Hasegawa.
630 * Alpha, SPARC, and IA-64 now also using floating stacks.
632 * Startup time of internationalized applications greatly improved through
633 iconv cache. Use iconvconfig to generate the cache file.
634 Contributed by Ulrich Drepper.
636 * The IA-64 specific part of ld.so was rewritten to eliminate some pretty
637 severe performance problems. Patch by David Mosberger.
639 * The Hurd port got a lot more functionality like AIO, various stdio
640 extensions, etc. Mainly done by Roland McGrath.
642 * mtrace can now lookup symbols in shared libraries.
646 * Intel's IA-64 math library is largely integrated. It provides fast and
647 accurate implementatations for most basic and standard math functions
648 in float, double, and long double format.
650 * Stephen Moshier implemented j0, j1, jn, y0, y1, yn, lgamma, erf, erfc,
651 and asin for the 96-bit long double format and asin, log, tan for the
652 128-bit long double format.
654 * The beginning of a last-bit accurate math library by IBM Haifa were added.
655 The basic double functions exist today. Contributed by Abraham Ziv
656 <ziv@il.ibm.com>, Moshe Olshansky <olshansk@il.ibm.com>, Ealan Henis
657 <ealan@il.ibm.com>, and Anna Reitman <reitman@il.ibm.com>.
659 * An asynchronous name lookup library was added. The interface is designed
660 after POSIX AIO. The proposal was circulated beforehand to get comments.
661 No negative ones came in. Implemented by Ulrich Drepper.
663 * Port to S390/64bit contributed by Martin Schwidefsky
664 <schwidefsky@de.ibm.com>.
666 * David Mosberger <davidm@hpl.hp.com> implemented the setcontext family
667 of functions for Linux/IA-64.
669 * The RPC code is now thread safe. Threads can now use the same service
670 of different services at the same time. Patch by Eric Norum
671 <eric.norum@usask.ca> with some help by Ulrich Drepper.
673 * Martin Schwidefsky <schwidefsky@de.ibm.com> implemented the setcontext
674 family of functions for Linux/S390.
676 * Ulrich Drepper <drepper@redhat.com> implemented the setcontext family
677 of functions for Linux/x86.
679 * Port to Linux/CRIS contributed by Axis Communications.
683 * Lots of headers were cleaned up. Using the tool in the conform/ subdir
684 we can now check for namespace violations and missing declarations. The
685 result is that almost all headers are now Unix-compliant (as defined in
686 the upcoming XPG6). The negative side is that some programs might need
687 corrections, too, if they depend on the incorrect form of the headers in
688 previous versions which defined too many symbols and included too many
691 * regex now handles multibyte character sets correctly.
692 Contributed by Isamu Hasegawa <isamu@yamato.ibm.com>.
694 * iconv (the program) does now conform to the upcoming XPG6 and handles
695 charmaps. Instead of the charset names the path of charmaps can be
696 provided and the conversion happens based on this data.
697 Contributed by Ulrich Drepper.
699 * The locale program now provides detailed information about the installed
704 only lists the names of the supported locales
708 provides details such as country, language, and codeset name.
709 Contributed by Ulrich Drepper.
713 * The gencat program now parses the input file according to the charset
714 selected by the LC_CTYPE category. This is important for stateful
715 character sets. To make generating catalogs easier there is a way
716 to overwrite the charset selected by the locale: before the first
717 message or $ quote line the catalog can contain a line like
721 to select the charset (ISO-8859-2 in this case).
723 Implemented by Shinya Hanataka and Ulrich Drepper.
725 * New codeset conversion modules: IBM-922 (Estonia PC codeset),
726 IBM-1124 (Ukraine PC codeset), IBM-1129 (Vietnamese PC codeset).
727 Contributed by Masahide Washizawa <washi@jp.ibm.com>.
729 * Optimized string functions for Alpha ev6 and ev67 by Richard Henderson
730 <rth@redhat.com> and Rick Gorton <rick.gorton@alpha-processor.com>.
732 * The LANGUAGE environment variable is now ignored unless the locale is
733 changed from the default "C" locale.
735 * The usual bug fixes.
739 * Greg McGary added runtime support for bounds checking using gcc's
740 new -fbounded-pointers option. ix86 target is complete. PowerPC
743 * Thorsten Kukuk added secure mode support to nscd.
745 * The Berkeley db libraries have been removed.
747 Related, the nss_db module is now in a separate package since it
748 obviously requires a database library being available.
750 * Wide character I/O streams implemented by Ulrich Drepper.
752 * Functions from the extended socket API added by Ulrich Drepper.
754 * Functions feenableexcept and fedisableexcept to control the
755 behaviour of individual exceptions have been added by Andreas Jaeger.
757 * ldconfig program added by Andreas Jaeger and Jakub Jelinek.
759 * The resolver code has been updated from bind 8.2.3-T5B which supports
760 threads. The integration was done by Andreas Jaeger, Adam D. Bradley,
763 This change could in some situations effect backward compatibility. Since
764 now `_res' is a thread-local instead of a global variable, modifying it
765 in one thread does not have any effect in other threads.
767 The resolver library was also extended to allow IPv6 as the transport
768 protocol for the requests. This work was done by Stig Venaas.
770 * Compatibility code for K&R C compilers has been removed from the
771 header files. A ISO C compiler is needed to use the library
772 (conforming to either C89 or C99 standard).
774 * Complete rewrite of the localedef program to support multibyte character
775 sets. Implement handling of ISO 14651 and ISO 14652. Rewrite strcoll,
776 strxfrm, wcscoll, and wcsxfrm functions. Make isw*() functions work.
777 Implemented by Ulrich Drepper.
779 Bruno Haible significantly improved the generation and use of the data
780 structures for the wide character tables.
782 * Plural handling in gettext implemented by Ulrich Drepper.
784 * The utmp daemon has been removed.
786 * The port to MIPS-Linux has been finished by Andreas Jaeger.
788 * A port to Hitachi SH3 and SH4 has been contributed by Kazumoto Kojima
791 * POSIX clocks and timers implemented by Kaz Kylheku and Ulrich Drepper.
793 * POSIX barriers implemented by Kaz Kylheku.
795 * POSIX spawn function family implemented by Ulrich Drepper.
797 * POSIX spinlocks are now available.
799 * Timed wait functions for mutex, rwlock, and semaphores are implemented.
801 * the configure option --enable-kernel=X.Y.Z allows to strip out
802 compatibility for kernel versions before X.Y.Z. This is currently only
803 implemented for Linux.
805 * the sockaddr_in6 structure changed. The IPv6 working group added a new
806 field sin6_scope_id. This means that all programs using IPv6 should be
807 recompiled. Don't expect binary compatibility with previous glibc
810 * various conversion modules for IBM character sets contributed by
813 * IA-64 port by Jes Sorensen and HJ Lu.

816 Compiling the GNU C Library for Linux/ia64
817 ******************************************
819 Please refer to the file INSTALL in the same directory as you found
820 this file for general information about configuring and compiling
823 For general inquiries about glibc under Linux/ia64 please use the
824 following mailing list linux-ia64@linuxia64.org or one of the relevant
827 Recommended Tools for Compilation
828 =================================
830 In order for glibc-2.2 to build correctly on the ia64 you need at
831 least the following versions of the GNU tools (the :
833 * The Cygnus toolchain snapshot for the ia64 as of August 4
834 including the provided set of patches. It is however recommend
835 you use the October 24 toolchain snapshot or a more recent version.
837 OR alternatively you can try the following (the Cygnus toolchain is
838 the recommended solution):
840 * GCC and binutils, GAS and GNU LD out of CVS from
841 sources.redhat.com as of August 28, 2000 or later. The CVS tree
842 may require special patches to work properly on the ia64.
844 Configuring and compiling GNU Libc for Linux/ia64
845 =================================================
847 The library requires Linux kernel version 2.4.0-test4-000728 or
848 later to funtion properly. Besides that it support for debug libraries
849 is currently untested. Hence the following options
850 are required for configuring the library:
852 --disable-debug --enable-kernel=2.4.0
854 It is also important that you make sure the library picks up the
855 appropriate kernel header files, if you do not have recent enough
856 kernel headers in /usr/src/linux/include, you should use the
857 --with-headers=<path> option to specify the location.
859 As an example I personally use the following options to configure
864 --enable-kernel=2.4.0
868 --with-headers=/home/jes/linux/include
873 Jes Sorensen <jes@linuxcare.com>,
875 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
889 * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
891 * New xdr functions are added; some rpc functions are now 64bit clean.
893 * Fixed a number of bugs and memory leaks (especially in NIS+ code).
895 * Fixed known incompatibilities with glibc 2.0.
897 * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
899 * Optimized a number of functions (especially the ELF dynamic loader).
901 * Update timezone data files.
903 * lots of charmaps corrections
905 * some new locale definitions and charmaps
910 * Richard Henderson corrected size of struct timeval on Linux/Alpha to
911 conform to POSIX member type requirements. Symbol versions have been
912 adjusted as needed within the library, and for direct use by applications,
913 but there is potential for problems if third-party libraries use
914 struct timeval as part of their interface. This does not present
915 a problem for X and other "essential" system libraries.
917 * An additional locale model to support C++ Standard Library locale
918 model and probably more was implemented by Ulrich Drepper.
920 * Eric Youngdale and Ulrich Drepper implemented versioning of objects on
923 * Miles Bader provided the `argp' function family to support hierachical
924 command line argument parsing, layered on top of getopt.
926 * strtod accepts new hexadecimal floating-point format from ISO C 9X.
928 * printf has two new specifiers %a and %A to print hexadecimal flaoting-point
931 * scanf recognizes the %a and %A format for scanning floating point numbers.
933 * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
934 information and interfaces for the available integer types.
936 * about 130 new math functions were added to implement the ISO C9x math
939 * the new header <complex.h> contains definitions of the complex math
940 functions from ISO C 9X.
942 * the new header <tgmath.h> defines generic macros to use complex or
943 real valued functions.
945 * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
947 * Andreas Jaeger provided a test suite for the math library.
949 * Mark Kettenis implemented the utmpx interface and an utmp daemon.
951 * Ulrich Drepper added character set conversion functions (iconv).
953 * Optimized string functions have been added.
955 * The localedata addon is now part of glibc.
957 * An implementation of profiling shared libraries was added by Ulrich Drepper.
959 * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
960 daemon for NSS (nscd).
962 Missing a better place here are some numbers on improvements. Under
963 Linux 2.1.125 un-tar-ing the kernel sources takes
967 using local files 12.19s 6.88s 22.91s
969 using NIS 13.92s 8.91s 26.34s
971 using NIS & nscd 10.37s 7.34s 25.30s
973 using NIS+ 27.57s 30.37s 640.46s
975 using NIS+ & nscd 10.25s 7.83s 26.51s
977 using NIS & old nscd [1] 13.83s 8.32s 29.60s
979 Keep in mind that non-namelookup related operations dominate above times.
980 It was just a common complain that using NIS+ unpacking the kernel is
983 [1] The old nscd implementation is not available anymore since it was
984 distributed with glibc up to version 2.0.98 and thus is now replaced.
986 * Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
988 * Mark Kettenis provided a Hesiod NSS module.
990 * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
991 and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
993 * rcmd can now handle netgroups (Dick Streefland).
995 * A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
998 * Support for the IPv6 protocol has been added to the socket API, as per the
999 latest draft standards.
1001 * Support for Linux 2.2 has been added.
1003 * Interface changes relative to the latest 2.0.x release:

1335 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1346 * inet_ntoa is thread-safe
1348 * updwtmp is moved from libutil to libc
1350 * rewrite of cbrt function
1352 * update of timezone data
1366 * add atoll function
1368 * fix complex problems in Berkeley DB code
1370 * fix math functions
1374 * fixed lots of header problems (especially Linux/GNU specific)
1376 * dynamic loader preserves all registers
1378 * Roland McGrath provided support for handling of auxiliary objects in
1379 the ELF dynamic loader.
1381 * support for parallel builds is improved
1385 * GNU extensions are no longer declared by default. To enable them you
1386 must define the macro `_GNU_SOURCE' in your program or compile with
1389 * The library has changed from using GNU ld symbol aliases to using weak
1390 symbols where available. The ELF object file format supports weak
1391 symbols; GNU ld also supports weak symbols in the a.out format. (There
1392 is also now support for other GNU ld extensions in ELF. Use the
1393 `--with-elf' option to configure to indicate you have ELF, and
1394 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
1395 of many files which contained only symbol aliases, reducing the size of
1396 the source and the compiled library; many other files were renamed to
1397 less cryptic names previously occupied by the symbol alias files.
1398 There is a new header file <elf.h> for programs which operate on
1399 files in the ELF format.
1401 * Converted to Autoconf version 2, so `configure' has more options.
1402 Run `configure --help' to see the details.
1404 * The library can now be configured to build profiling, highly-optimized
1405 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
1406 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
1407 `configure' enable building these extra libraries. The shared library is
1408 built by default when using both ELF and GNU ld. When shared libraries
1409 are enabled, the new library `-ldl' is available for arbitrary run-time
1410 loading of shared objects; its interface is defined in <dlfcn.h>. The
1411 new header file <link.h> gives access to the internals of the run-time
1412 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
1413 application of same name on other systems and it provides information
1414 about dynamically linked binaries.
1416 * The C library now provides the run-time support code for profiling
1417 executables compiled with `-pg'. Programs can control the profiling code
1418 through the interface in <sys/gmon.h>. The `gmon.out' files written by
1419 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
1420 the support for this file format was contributed by David Mosberger-Tang.
1422 * The math code has been replaced with a math library based on fdlibm from
1423 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
1424 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
1425 functions. The math functions now reside in a separate library, so
1426 programs using them will need to use `-lm' their linking commands.
1428 * John C. Bowman contributed optimized ix87 assembler inline functions.
1430 * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
1431 mechanism similar to that found in Solaris 2. This is now used for the
1432 group, passwd, hosts, networks, services, protocols, rpc, ethers,
1433 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
1434 file controls what services are used for each individual database. This
1435 works by loading shared libraries with names specified in `nsswitch.conf',
1436 so service modules can be changed or added at any time without even
1437 relinking any program. Currently there are the file, db, and NIS based
1438 NSS services available.
1440 * The new functions `strtoq' and `strtouq' parse integer values from
1441 strings, like `strtol' and `strtoul', but they return `long long int' and
1442 `unsigned long long int' values, respectively (64-bit quantities).
1444 * The new functions `strtof' and `strtold' parse floating-point values from
1445 strings, like `strtod', but they return `float' and `long double' values,
1446 respectively (on some machines `double' and `long double' are the same).
1448 * Ulrich Drepper has contributed new implementations of the floating-point
1449 printing and reading code used in the `printf' family of functions and
1450 `strtod', `strtof', and `strtold'. These new functions are perfectly
1451 accurate, and much faster than the old ones.
1453 * The implementation of the POSIX locale model was completely rewritten by
1454 Ulrich Drepper. This includes the new programs `localedef' and `locale'
1455 to compile the POSIX locale definition.
1457 * The former dummy implementations of the strcoll and strxfrm function are
1458 now replaced by fully functional code contributed by Ulrich Drepper. The
1459 collation information comes from the POSIX locale definitions.
1461 * The new header <langinfo.h> defines an interface for accessing
1462 various locale-dependent data (using the locale chosen with `setlocale').
1464 * Ulrich Drepper has contributed a new suite of functions for operation on
1465 wide-character and multibyte-character strings, in <wchar.h>;
1466 and classification and case conversion of wide characters, in <wctype.h>.
1467 These new functions are conforming to the ISO C, Amendement 1 specification.
1469 * There is now a second implementation of the standard I/O library available.
1470 It comes from GNU libg++ as was written by Per Bothner, heavily modified
1471 by Hongjiu Lu and made thread safe by Ulrich Drepper.
1473 * You can now use positional parameter specifications in format strings
1474 for the `printf' and `scanf' families of functions. For example,
1475 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
1476 ``Number 6, Mr Jones''. This is mainly useful when providing different
1477 format strings for different languages, whose grammars may dictate
1478 different orderings of the values being printed. To support this
1479 feature, the interface for `register_printf_handler' has changed; see
1480 the header file <printf.h> for details.
1482 * The `printf' and `scanf' families of functions now understand a new
1483 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
1484 to group numbers as indicated by the locale; for `scanf' and friends, this
1485 says to accept as valid only a number with all the proper grouping
1486 separators in the right places. In the default "C" locale, numbers are
1487 not grouped; but locales for specific countries will define the usual
1488 conventions (i.e. separate thousands with `,' in the US locale).
1490 * The pgrp functions have been regularized, slightly incompatibly but much
1491 less confusingly. The core functions are now `getpgid' and `setpgid',
1492 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
1493 argument) and BSD `setpgrp' (identical to `setpgid') functions are
1494 provided for compatibility. There is no longer an incompatible `getpgrp'
1495 with an argument declared under _BSD_SOURCE; no BSD code uses it.
1497 * The new header file <fts.h> and suite of functions simplify programs that
1498 operate on directory trees. This code comes from 4.4 BSD.
1500 * The resolver code has been updated from the BIND 4.9.5-P1 release.
1501 Parts of the code were heavily modified by Ulrich Drepper to fit in the
1502 NSS scheme used in glibc.
1504 * There is a new malloc debugging hook `__memalign_hook'.
1506 * There are new typedefs `ushort' for `unsigned short int' and `uint' for
1507 `unsigned int' in <sys/types.h>. These are for compatibility only and
1508 their use is discouraged.
1510 * The `-lmcheck' library to enable standard malloc debugging hooks is now
1511 done differently, so that it works even without GNU ld.
1513 * New function `euidaccess' checks allowed access to a file like `access',
1514 but using the effective IDs instead of the real IDs.
1516 * The time zone data files have been updated for the latest and greatest
1517 local time conventions of the countries of the world.
1519 * The new function `dirfd' extracts the file descriptor used by a DIR stream;
1522 * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
1523 for formatting floating-point numbers. They are provided only for
1524 compatibility; new programs should use `sprintf' instead. There are
1525 also equivalent function for the `long double' floating-point type and
1526 all functions also exist in a reentrant form.
1528 * The new auxiliary library `-lutil' from 4.4 BSD contains various
1529 functions for maintaining the login-record files (primarily of use to
1530 system programs such as `login'), and convenient functions for
1531 allocating and initializing a pseudo-terminal (pty) device.
1533 * Ulrich Drepper has contributed new support for System V style
1534 shared memory and IPC on systems that support it.
1536 * Ulrich Drepper has contributed several miscellaneous new functions found
1537 in System V: The `hsearch' family of functions provide an effective
1538 implementation of hash tables; `a64l' and `l64a' provide a very simple
1539 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
1542 * Ulrich Drepper has contributed new reentrant counterparts for the
1543 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
1545 * Ulrich Drepper has contributed new, highly-optimized versions of several
1546 string functions for the i486/Pentium family of processors.
1548 * Ulrich Drepper has updated the Linux-specific code, based largely
1549 on work done in Hongjiu Lu's version of GNU libc for Linux.
1550 The GNU library now supports Linux versions 2.0.10 and later,
1551 using the ELF object file format (i[3456]86-*-linux).
1553 * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
1555 * David Mosberger-Tang and Richard Henderson have ported the C library
1556 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
1557 dynamic linking support for ELF/Alpha.
1559 * Richard Henderson contributed several Alpha optimized assembler function
1560 for arithmetic and string handling.
1562 * Ulrich Drepper has contributed a new set of message catalog functions to
1563 support multiple languages using the <libintl.h> interface, for use with
1564 his new package GNU gettext. Translation volunteers have contributed
1565 catalogs of the library's messages in Spanish, German, and Korean.
1567 * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
1568 program and the `catgets' function for reading the catalog files it
1569 creates. (The <libintl.h> interface is preferred; we include the
1570 <nl_types.h> interface using `catgets' only for source compatibility with
1571 programs already written to use it.)
1573 * New header file <values.h> gives SVID-compatible names for <limits.h>
1576 * Various new macros, declarations, and small header files for compatibility
1579 * New function `group_member' is a convenient way to check if a process has
1580 a given effective group ID.
1582 * When using GCC 2.7 and later, the socket functions are now declared in a
1583 special way so that passing an argument of type `struct sockaddr_in *',
1584 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
1585 `struct sockaddr *' type, does not generate a type-clash warning.
1587 * New function `error' declared in header file <error.h> is a convenient
1588 function for printing error messages and optionally exiting; this is the
1589 canonical function used in GNU programs. The new functions `err', `warn',
1590 and friends in header file <err.h> are the canonical 4.4 BSD interface for
1591 doing the same thing.
1593 * The <glob.h> interface has several new flags from 4.4 BSD that extend the
1594 POSIX.2 `glob' function to do ~ and {...} expansion.
1596 * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
1597 `clearenv' which is used in POSIX.9 is also available.
1599 * New function `getsid' returns session ID number on systems that support it.
1601 * We have incorporated the 4.4 BSD `db' library (version 1.85). New header
1602 files <db.h> and <mpool.h> provide a rich set of functions for several
1603 types of simple databases stored in memory and in files, and <ndbm.h> is
1604 an old `ndbm'-compatible interface using the `db' functions. Link with
1605 `-ldb' to get these functions.
1607 * New macro `strdupa' copies a string like `strdup', but uses local stack
1608 space from `alloca' instead of dynamic heap space from `malloc'.
1610 * New function `strnlen' is like `strlen' but searches only a given maximum
1611 number of characters for the null terminator. `stpncpy', `strndup' and
1612 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
1615 * New function `statfs' in header <sys/statfs.h>.
1617 * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
1618 provide convenient functions for operating on blocks of null-terminated
1621 * A new suite of functions in <utmp.h> handle all the details of reading
1622 and writing the utmp file.
1624 * An implementation of the NIS/YP(tm) based NSS service was contributed by
1627 * Paul Eggert and Ulrich Drepper modified the `strftime' function to be
1628 completely POSIX compliant and also implemented the extended functionality
1629 to handle alternate digit representation and alternate era date formats.
1631 * Ulrich Drepper provided an implementation of the `strptime' function
1632 defined in XPG4.2 which transforms a string into a `struct tm' value.
1634 * Paul Eggert provided the tzselect shell script as part of the timezone
1635 code. The shell script makes it easy to select the correct timezone
1638 * The implementation of the malloc family of functions is completely replaced
1639 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
1640 The implementation uses the mmap function (if available) and it is
1641 optimized for the use in multi threaded programs.
1643 * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
1644 functions. This new functionality is usable by specifying a special
1645 salt string and it is compatible with implementation on *BSD systems.
1647 * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
1648 `getsubopt' to handle second level command line options, `bsd_signal'
1649 to access BSD style `signal' functionality, the obsolete `regexp' style
1652 * the `lchown' function is available on system which support this
1655 * The implementation of the shadow password handling function was contributed
1658 * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
1660 * POSIX.1g support was added. The <sys/select.h> header is available,
1661 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
1662 implementation of `getaddrinfo'.
1666 * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
1668 * New header file <fstab.h> and new functions `getfsspec', `getfsent' and
1669 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
1671 * The new function `daemon' from 4.4 BSD is useful for server programs that
1672 want to put themselves in the background.
1674 * Joel Sherrill has contributed support for several standalone boards that
1675 run without an operating system.
1677 * `printf', `scanf' and friends now accept a `q' type modifier for long
1678 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
1680 * All of the code taken from BSD (notably most of the math and networking
1681 routines) has been updated from the BSD 4.4-Lite release.
1683 * The resolver code has been updated from the BIND-4.9.3-BETA9 release.
1685 * The new functions `getdomainname' and `setdomainname' fetch or change the
1686 YP/NIS domain name. These are system calls which exist on systems which
1689 * The time zone data files have been updated for the latest international
1692 * The SunRPC programs `portmap' and `rpcinfo' are now installed in
1693 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
1697 * The C library now includes support for Sun RPC, from Sun's free
1698 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
1699 are included. (There is still no support for YP.)
1701 * Tom Quinn has contributed a port of the C library to SGI machines running
1702 Irix 4 (mips-sgi-irix4).
1704 * The new `lockf' function is a simplified interface to the locking
1705 facilities of `fcntl', included for compatibility.
1707 * New time functions `timegm', `timelocal', and `dysize' for compatibility.
1709 * New header file <sys/timeb.h> and new function `ftime' for compatibility.
1711 * New header files <poll.h> and <sys/poll.h> and new function `poll' for
1714 * The error message printed by `assert' for a failed assertion now includes
1715 the name of the program (if using GNU ld) and the name of the calling
1716 function (with versions of GCC that support this).
1718 * The `psignal' function is now declared in <signal.h>, not <stdio.h>.
1720 * The library now includes the <sys/mman.h> header file and memory
1721 management functions `mmap', `munmap', `mprotect', `msync', and
1722 `madvise', on systems that support those facilities.
1724 * The interface for `mcheck' has changed slightly: the function called to
1725 abort the program when an allocation inconsistency is detected now takes
1726 an argument that indicates the type of failure. The new function
1727 `mprobe' lets you request a consistency check for a particular block at
1728 any time (checks are normally done only when you call `free' or `realloc'
1731 * It is now possible to easily cross-compile the C library, building on one
1732 system a library to run on another machine and/or operating system. All
1733 you need to do is set the variable `HOST_CC' in `configparms' to the
1734 native compiler for programs to run on the machine you are building on (a
1735 few generator programs are used on Unix systems); set `CC' to the
1738 * The new function `fexecve' (only implemented on the GNU system) executes
1739 a program file given a file descriptor already open on the file.
1743 * Brendan Kehoe has contributed most of a port to the DEC Alpha
1744 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
1746 * You can set the variable `libprefix' in `configparms' to specify a prefix
1747 to be prepended to installed library files; this makes it easy to install
1748 the GNU C library to be linked as `-lgnuc' or whatever.
1750 * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
1751 copies a limited number of characters from a string, and returns the
1752 address of the last character written.
1754 * You no longer need to check for whether the installed `stddef.h' is
1755 compatible with the GNU C library. configure now checks for you.
1757 * You can now define a per-stream `fileno' function to convert the
1758 stream's cookie into an integral file descriptor.
1760 * ``malloc (0)'' no longer returns a null pointer. Instead, it
1761 allocates zero bytes of storage, and returns a unique pointer which
1762 you can pass to `realloc' or `free'. The behavior is undefined if
1763 you dereference this pointer.
1765 * The C library now runs on Sony NEWS m68k machines running either
1766 NewsOS 3 or NewsOS 4.
1768 * The new `syscall' function is a system-dependent primitive function
1769 for invoking system calls. It has the canonical behavior on Unix
1770 systems, including unreliable return values for some calls (such as
1771 `pipe', `fork' and `getppid').
1773 * The error code `EWOULDBLOCK' is now obsolete; it is always defined
1774 to `EAGAIN', which is the preferred name. On systems whose kernels
1775 use two distinct codes, the C library now translates EWOULDBLOCK to
1776 EAGAIN in every system call function.
1780 * The GNU C Library Reference Manual is now distributed with the library.
1781 `make dvi' will produce a DVI file of the printed manual.
1782 `make info' will produce Info files that you can read on line using C-h i
1783 in Emacs or the `info' program.
1784 Please send comments on the manual to bug-glibc-manual@gnu.org.
1786 * The library now supports SVR4 on i386s (i386-unknown-sysv4).
1788 * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
1790 * Jason Merrill has contributed a port to the Sequent Symmetry running
1791 Dynix version 3 (i386-sequent-dynix).
1793 * The library has been ported to i386s running SCO 3.2.4 (also known as SCO
1794 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
1796 * New function `memory_warnings' lets you arrange to get warnings when
1797 malloc is running out of memory to allocate, like Emacs gives you.
1799 * The C library now contains the relocating allocator used in Emacs 19 for
1800 its editing buffers. This allocator (ralloc) minimizes allocation
1801 overhead and fragmentation by moving allocated regions around whenever it
1802 needs to. You always refer to a ralloc'd region with a "handle" (a
1803 pointer to a pointer--an object of type `void **').
1805 * There is a new `printf' format: `%m' gives you the string corresponding
1806 to the error code in `errno'.
1808 * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
1809 or `%[' conversion, but instead of filling in a fixed-sized buffer you
1810 pass, the `a' modifier says to fill in a `char **' you pass with a
1813 * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
1814 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
1815 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
1817 * `mkstemp' is a traditional Unix function to atomically create and open a
1818 uniquely-named temporary file.
1822 * The standard location for the file that says what the local timezone is
1823 has changed again. It is now `/usr/local/etc/localtime' (or more
1824 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
1826 * The distribution no longer contains any files with names longer than 14
1829 * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
1830 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
1832 * New functions `ttyslot' and `syslog' from 4.4 BSD.
1836 * The configuration process has changed quite a bit. The `configure'
1837 script is now used just like the configuration scripts for other GNU
1838 packages. The `sysdeps' directory hierarchy is much rearranged.
1839 The file `INSTALL' explains the new scheme in detail.
1841 * The header files no longer need to be processed into ANSI C and
1842 traditional C versions. There is just one set of files to install, and
1843 it will work with ANSI or old C compilers (including `gcc -traditional').
1845 * Brendan Kehoe and Ian Lance Taylor have ported the library to the
1846 MIPS DECStation running Ultrix 4.
1848 * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
1849 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
1850 made itself into a shared library.
1852 * Yet further improved support for the i386, running 4.3 BSD-like systems
1853 (such as Mach 3 with the Unix single-server), or System V.
1855 * New function `strncasecmp' to do case-insensitive string comparison
1856 with limited length.
1858 * New function `strsep' is a reentrant alternative to `strtok'.
1860 * New functions `scandir' and `alphasort' for searching directories.
1862 * New function `setenv' is a better interface to `putenv'.
1864 * Ian Lance Taylor has contributed an implementation of the SVID `ftw'
1865 function for traversing a directory tree.
1867 * The GNU obstack package is now also part of the C library.
1868 The new function `open_obstack_stream' creates a stdio stream that
1869 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
1870 formatted output directly to an obstack.
1872 * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
1873 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
1875 * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
1877 * The new functions `strfry' and `memfrob' do mysterious and wonderful
1878 things to your strings.
1880 * There are some new test programs: test-fseek, testmb, and testrand.
1882 * Some work has been done to begin porting the library to 4.4 BSD and Linux.
1883 These ports are not finished, but are a good starting place for really
1884 supporting those systems.
1886 * `/etc/localtime' is now the standard location for the file that says what
1887 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
1888 This follows the general principle that `/etc' is the place for all local
1889 configuration files.
1891 * The C library header files now use `extern "C"' when used by the C++
1892 compiler, so the C library should now work with C++ code.
1894 * The header file <bstring.h> is gone. <string.h> now declares bcopy,
1895 bcmp, bzero, and ffs. (Update: nowadays these functions are declared
1898 * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
1899 function which uses the `merge sort' algorithm, and is said to be
1900 significantly faster than the old GNU `qsort' function. Merge sort is
1901 now the standard `qsort' function. The new algorithm can require a lot
1902 of temporary storage; so, the old sorting function is called when the
1903 required storage is not available.
1905 * The C library now includes Michael Glad's Ultra Fast Crypt, which
1906 provides the Unix `crypt' function, plus some other entry points.
1908 * The code and header files taken from 4.4 BSD have been updated with the
1909 latest files released from Berkeley.
