38 * The dynamic linker now recognizes supported ABI versions from the
39 EI_ABIVERSION field in the ELF header.
40 Implemented by Ulrich Drepper.
42 * New NIS mode selector ADJUNCT_AS_SHADOW. The passwd.adjunct.byname table
43 will not be used to fill in password fields in the passwd.byname replies.
44 Instead it is used to synthesize the shadow.byname table, should it be
45 missing. This is a useful mode in some installations involving Solaris.
46 Implemented by Ulrich Drepper.

66 frame would be created. Implemented by Ulrich Drepper.
68 * STT_GNU_IFUNC is now supported in static executables.
69 Implemented by H.J. Lu.
71 * STT_GNU_IFUNC implemented for PPC by Alan Modra.
73 * New optimized string functions for x86-64: strstr, strcasestr, memcmp,
74 strcspn, strpbrk, strspn, strcpy, stpcpy, strncpy, strcmp (SSE2, SSE4.2),
75 strncmp (SSE2, SSE4.2), strchr (SSE4.2), strrchr (SSE4.2).
76 Contributed by H.J. Lu.
78 strlen, rawmemchr, strcmp (SSSE3), strncmp (SSSE3).
79 Implemented by Ulrich Drepper.
81 * New optimized string functions for x86: strlen, strcspn, strspn, strpbrk,
83 Contributed by H.J. Lu.

86 Implemented by H.J. Lu and Ulrich Drepper.
88 * AVX support in x86-64 auditing support in ld.so.
89 Implemented by H.J. Lu.
91 * STB_GNU_UNIQUE support added.
92 Implemented by Ulrich Drepper.
94 * Implement second fallback mode for optimized DNS lookup for even more
95 broken environments. If two requests from the same port are not
96 handled correctly close the socket and open a new one before sending
97 the second request. The 'single-request-reopen' option in /etc/resolv.conf
98 can be used to select this mode right away, instead of rediscovering the
99 necessity is every process again.
100 Implemented by Ulrich Drepper.
102 * New resolver flag RES_USE_DNSSEC to enable use of verified lookup.
103 Implemented by Adam Tkac.
105 * Optimized iconv conversions for S390x.

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

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

244 vdprintf, and obstack_vprintf.
245 Implemented by Jakub Jelinek.
247 * Faster memset for x86-64.
248 Implemented by Harsha Jagasia and H.J. Lu.
250 * Faster memcpy on x86.
251 Implemented by Ulrich Drepper.
253 * ARG_MAX is not anymore constant on Linux. Use sysconf(_SC_ARG_MAX).

312 3352, 3363, 3369, 3426, 3427, 3429, 3451, 3458, 3465, 3480, 3483, 3493,
313 3514, 3515, 3559, 3632, 3664, 3673, 3674, 3745, 3747, 3818, 3840, 3842,

338 3225, 3251, 3252, 3253, 3273
340 * For Linux, the sorting of addresses returned by getaddrinfo now also
341 handles rules 3, 4, and 7 from RFC 3484. I.e., all rules are handled.
342 Implemented by Ulrich Drepper.
344 * Allow system admin to configure getaddrinfo with the /etc/gai.conf file.
345 Implemented by Ulrich Drepper.
347 * New Linux interfaces: splice, tee, sync_file_range, vmsplice.
349 * New iconv module for MIK. Contributed by Alexander Shopov.
351 * For sites with broken group and/or passwd database, the auto-propagate
352 option of nscd can prevent creating ID lookup entries from the results
353 of a name lookup and vice versa. This usually is no problem but some
354 site might have problems with the default behavior.
355 Implemented by Ulrich Drepper.
357 * Iterating over entire database in NIS can be slow. With the
358 SETENT_BATCH_READ option in /etc/default/nss a system admin can decide
359 to trade time for memory. The entire database will be read at once.
360 Implemented by Ulrich Drepper.
362 * The interfaces introduced in RFC 3542 have been implemented by
365 * Support for the new ELF hash table format was added by Ulrich Drepper.
367 * Support for priority inheritance mutexes added by Jakub Jelinek and
370 * Support for priority protected mutexes added by Jakub Jelinek.
372 * New locales: nr_ZA, pa_PK, ca_AD, ca_FR, ca_IT, el_CY, tr_CY, as_IN,
373 or_IN, csb_PL, fy_NL, sr_ME.
377 * More overflow detection functions.
379 * New iconv converters for IBM1025, IBM1122, IBM1137, IBM1153,
380 IBM1154, IBM1155, IBM1156, IBM1157, and IBM1158 contributed by Jiro Sekiba.
382 More converters for IBM803, IBM901, IBM902, IBM921, IBM1008, IBM1097,

385 IBM4899, IBM4909, IBM4971, IBM5347, IBM9030, IBM9066, IBM9448, IBM12712,
386 IBM16804, IBM1364, IBM1371, IBM1388, IBM1390, and IBM1399 contributed
387 by Masahide Washizawa.
389 * It is now possible to install audit libraries for the dynamic linker using
390 LD_AUDIT. Implemented by Ulrich Drepper.
392 * The LinuxThreads add-on, providing pthreads on Linux 2.4 kernels, is no
393 longer supported. The new NPTL implementation requires Linux 2.6 kernels.
394 For a libc and libpthread that works well on Linux 2.4 kernels, we
395 recommend using the stable 2.3 branch.
397 * The new function open_wmemstream acts like open_memstream,
398 but uses a wchar_t wide character buffer.
400 * The new function ppoll is an improved version of poll, similar to pselect.
402 * New interfaces: fdopendir, openat, fstatat, fchmodat, fchownat,
403 futimesat, faccessat, mkdirat, mkfifoat, mknodat,
404 renameat, unlinkat, linkat, symlinkat, readlinkat.
406 * New Linux kernel system calls: unshare,
407 inotify_init, inotify_add_watch, inotify_rm_watch.
409 * The euidaccess function is now also known by the alias eaccess,
410 for compatibility with some other systems.
412 * Timezone data updated to 2006b version.
416 * The following bugs are resolved with this release:

427 * As of this release, GCC 4 can be used to compile the C Library.
429 * Timezone data updated to 2005m version.
433 * The following bugs are resolved with this release:
435 284, 592, 602, 626, 633, 640, 650, 661, 671, 681, 693, 700, 710, 719,

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

823 Compiling the GNU C Library for Linux/ia64
824 ******************************************
826 Please refer to the file INSTALL in the same directory as you found
827 this file for general information about configuring and compiling
830 For general inquiries about glibc under Linux/ia64 please use the
831 following mailing list linux-ia64@linuxia64.org or one of the relevant
834 Recommended Tools for Compilation
835 =================================
837 In order for glibc-2.2 to build correctly on the ia64 you need at
838 least the following versions of the GNU tools (the :
840 * The Cygnus toolchain snapshot for the ia64 as of August 4
841 including the provided set of patches. It is however recommend
842 you use the October 24 toolchain snapshot or a more recent version.
844 OR alternatively you can try the following (the Cygnus toolchain is
845 the recommended solution):
847 * GCC and binutils, GAS and GNU LD out of CVS from
848 sources.redhat.com as of August 28, 2000 or later. The CVS tree
849 may require special patches to work properly on the ia64.
851 Configuring and compiling GNU Libc for Linux/ia64
852 =================================================
854 The library requires Linux kernel version 2.4.0-test4-000728 or
855 later to funtion properly. Besides that it support for debug libraries
856 is currently untested. Hence the following options
857 are required for configuring the library:
859 --disable-debug --enable-kernel=2.4.0
861 It is also important that you make sure the library picks up the
862 appropriate kernel header files, if you do not have recent enough
863 kernel headers in /usr/src/linux/include, you should use the
864 --with-headers=<path> option to specify the location.
866 As an example I personally use the following options to configure
871 --enable-kernel=2.4.0
875 --with-headers=/home/jes/linux/include
880 Jes Sorensen <jes@linuxcare.com>,
882 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
896 * New ISO C 9x function _Exit, imaxabs, and imaxdiv are added.
898 * New xdr functions are added; some rpc functions are now 64bit clean.
900 * Fixed a number of bugs and memory leaks (especially in NIS+ code).
902 * Fixed known incompatibilities with glibc 2.0.
904 * New functions lock64, strchrnul, rawmemchr, getutmp and getutmpx.
906 * Optimized a number of functions (especially the ELF dynamic loader).
908 * Update timezone data files.
910 * lots of charmaps corrections
912 * some new locale definitions and charmaps
917 * Richard Henderson corrected size of struct timeval on Linux/Alpha to
918 conform to POSIX member type requirements. Symbol versions have been
919 adjusted as needed within the library, and for direct use by applications,
920 but there is potential for problems if third-party libraries use
921 struct timeval as part of their interface. This does not present
922 a problem for X and other "essential" system libraries.
924 * An additional locale model to support C++ Standard Library locale
925 model and probably more was implemented by Ulrich Drepper.
927 * Eric Youngdale and Ulrich Drepper implemented versioning of objects on
930 * Miles Bader provided the `argp' function family to support hierachical
931 command line argument parsing, layered on top of getopt.
933 * strtod accepts new hexadecimal floating-point format from ISO C 9X.
935 * printf has two new specifiers %a and %A to print hexadecimal flaoting-point
938 * scanf recognizes the %a and %A format for scanning floating point numbers.
940 * the new headers <stdint.h> and <inttypes.h> from ISO C 9X provides
941 information and interfaces for the available integer types.
943 * about 130 new math functions were added to implement the ISO C9x math
946 * the new header <complex.h> contains definitions of the complex math
947 functions from ISO C 9X.
949 * the new header <tgmath.h> defines generic macros to use complex or
950 real valued functions.
952 * Thorsten Kukuk provided an implementation for NIS+, securelevel 0, 1 and 2.
954 * Andreas Jaeger provided a test suite for the math library.
956 * Mark Kettenis implemented the utmpx interface and an utmp daemon.
958 * Ulrich Drepper added character set conversion functions (iconv).
960 * Optimized string functions have been added.
962 * The localedata addon is now part of glibc.
964 * An implementation of profiling shared libraries was added by Ulrich Drepper.
966 * Thorsten Kukuk and Ulrich Drepper provided an implementation for a caching
967 daemon for NSS (nscd).
969 Missing a better place here are some numbers on improvements. Under
970 Linux 2.1.125 un-tar-ing the kernel sources takes
974 using local files 12.19s 6.88s 22.91s
976 using NIS 13.92s 8.91s 26.34s
978 using NIS & nscd 10.37s 7.34s 25.30s
980 using NIS+ 27.57s 30.37s 640.46s
982 using NIS+ & nscd 10.25s 7.83s 26.51s
984 using NIS & old nscd [1] 13.83s 8.32s 29.60s
986 Keep in mind that non-namelookup related operations dominate above times.
987 It was just a common complain that using NIS+ unpacking the kernel is
990 [1] The old nscd implementation is not available anymore since it was
991 distributed with glibc up to version 2.0.98 and thus is now replaced.
993 * Tim Waugh provided an implementation of the POSIX.2 wordexp function family.
995 * Mark Kettenis provided a Hesiod NSS module.
997 * The ELF dynamic loader knows how to process dynamic string tokens ($ORIGIN
998 and $PLATFORM) in RPATHs and similar strings (Ulrich Drepper).
1000 * rcmd can now handle netgroups (Dick Streefland).
1002 * A port to the ARM was contributed by Phil Blundell, Pat Beirne and Scott
1005 * Support for the IPv6 protocol has been added to the socket API, as per the
1006 latest draft standards.
1008 * Support for Linux 2.2 has been added.
1010 * Interface changes relative to the latest 2.0.x release:

1342 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
1353 * inet_ntoa is thread-safe
1355 * updwtmp is moved from libutil to libc
1357 * rewrite of cbrt function
1359 * update of timezone data
1373 * add atoll function
1375 * fix complex problems in Berkeley DB code
1377 * fix math functions
1381 * fixed lots of header problems (especially Linux/GNU specific)
1383 * dynamic loader preserves all registers
1385 * Roland McGrath provided support for handling of auxiliary objects in
1386 the ELF dynamic loader.
1388 * support for parallel builds is improved
1392 * GNU extensions are no longer declared by default. To enable them you
1393 must define the macro `_GNU_SOURCE' in your program or compile with
1396 * The library has changed from using GNU ld symbol aliases to using weak
1397 symbols where available. The ELF object file format supports weak
1398 symbols; GNU ld also supports weak symbols in the a.out format. (There
1399 is also now support for other GNU ld extensions in ELF. Use the
1400 `--with-elf' option to configure to indicate you have ELF, and
1401 `--with-gnu-ld' if using GNU ld.) This change resulted in the deletion
1402 of many files which contained only symbol aliases, reducing the size of
1403 the source and the compiled library; many other files were renamed to
1404 less cryptic names previously occupied by the symbol alias files.
1405 There is a new header file <elf.h> for programs which operate on
1406 files in the ELF format.
1408 * Converted to Autoconf version 2, so `configure' has more options.
1409 Run `configure --help' to see the details.
1411 * The library can now be configured to build profiling, highly-optimized
1412 (but undebuggable), and/or shared libraries (ELF with GNU ld only). The
1413 `--enable-profile', `--enable-omitfp', and `--enable-shared' options to
1414 `configure' enable building these extra libraries. The shared library is
1415 built by default when using both ELF and GNU ld. When shared libraries
1416 are enabled, the new library `-ldl' is available for arbitrary run-time
1417 loading of shared objects; its interface is defined in <dlfcn.h>. The
1418 new header file <link.h> gives access to the internals of the run-time
1419 dynamic linker, `ld.so'. The shell script `ldd' is similar to the
1420 application of same name on other systems and it provides information
1421 about dynamically linked binaries.
1423 * The C library now provides the run-time support code for profiling
1424 executables compiled with `-pg'. Programs can control the profiling code
1425 through the interface in <sys/gmon.h>. The `gmon.out' files written by
1426 the GNU C library can be read only by GNU `gprof' (from GNU binutils);
1427 the support for this file format was contributed by David Mosberger-Tang.
1429 * The math code has been replaced with a math library based on fdlibm from
1430 Sun, and modified by JT Conklin and Ulrich Drepper with i387 support, by
1431 Ian Taylor with `float' functions and by Ulrich Drepper with `long double'
1432 functions. The math functions now reside in a separate library, so
1433 programs using them will need to use `-lm' their linking commands.
1435 * John C. Bowman contributed optimized ix87 assembler inline functions.
1437 * Ulrich Drepper has contributed support for an `/etc/nsswitch.conf'
1438 mechanism similar to that found in Solaris 2. This is now used for the
1439 group, passwd, hosts, networks, services, protocols, rpc, ethers,
1440 shadow, netgroup, publickey, and alias databases. The `nsswitch.conf'
1441 file controls what services are used for each individual database. This
1442 works by loading shared libraries with names specified in `nsswitch.conf',
1443 so service modules can be changed or added at any time without even
1444 relinking any program. Currently there are the file, db, and NIS based
1445 NSS services available.
1447 * The new functions `strtoq' and `strtouq' parse integer values from
1448 strings, like `strtol' and `strtoul', but they return `long long int' and
1449 `unsigned long long int' values, respectively (64-bit quantities).
1451 * The new functions `strtof' and `strtold' parse floating-point values from
1452 strings, like `strtod', but they return `float' and `long double' values,
1453 respectively (on some machines `double' and `long double' are the same).
1455 * Ulrich Drepper has contributed new implementations of the floating-point
1456 printing and reading code used in the `printf' family of functions and
1457 `strtod', `strtof', and `strtold'. These new functions are perfectly
1458 accurate, and much faster than the old ones.
1460 * The implementation of the POSIX locale model was completely rewritten by
1461 Ulrich Drepper. This includes the new programs `localedef' and `locale'
1462 to compile the POSIX locale definition.
1464 * The former dummy implementations of the strcoll and strxfrm function are
1465 now replaced by fully functional code contributed by Ulrich Drepper. The
1466 collation information comes from the POSIX locale definitions.
1468 * The new header <langinfo.h> defines an interface for accessing
1469 various locale-dependent data (using the locale chosen with `setlocale').
1471 * Ulrich Drepper has contributed a new suite of functions for operation on
1472 wide-character and multibyte-character strings, in <wchar.h>;
1473 and classification and case conversion of wide characters, in <wctype.h>.
1474 These new functions are conforming to the ISO C, Amendement 1 specification.
1476 * There is now a second implementation of the standard I/O library available.
1477 It comes from GNU libg++ as was written by Per Bothner, heavily modified
1478 by Hongjiu Lu and made thread safe by Ulrich Drepper.
1480 * You can now use positional parameter specifications in format strings
1481 for the `printf' and `scanf' families of functions. For example,
1482 `printf ("Number %2$d, Mr %1$s\n", "Jones", 6);'' prints
1483 ``Number 6, Mr Jones''. This is mainly useful when providing different
1484 format strings for different languages, whose grammars may dictate
1485 different orderings of the values being printed. To support this
1486 feature, the interface for `register_printf_handler' has changed; see
1487 the header file <printf.h> for details.
1489 * The `printf' and `scanf' families of functions now understand a new
1490 formatting flag for numeric conversions: the ' flag (e.g. %'d or %'f) says
1491 to group numbers as indicated by the locale; for `scanf' and friends, this
1492 says to accept as valid only a number with all the proper grouping
1493 separators in the right places. In the default "C" locale, numbers are
1494 not grouped; but locales for specific countries will define the usual
1495 conventions (i.e. separate thousands with `,' in the US locale).
1497 * The pgrp functions have been regularized, slightly incompatibly but much
1498 less confusingly. The core functions are now `getpgid' and `setpgid',
1499 which take arguments for the PID to operate on; the POSIX.1 `getpgrp' (no
1500 argument) and BSD `setpgrp' (identical to `setpgid') functions are
1501 provided for compatibility. There is no longer an incompatible `getpgrp'
1502 with an argument declared under _BSD_SOURCE; no BSD code uses it.
1504 * The new header file <fts.h> and suite of functions simplify programs that
1505 operate on directory trees. This code comes from 4.4 BSD.
1507 * The resolver code has been updated from the BIND 4.9.5-P1 release.
1508 Parts of the code were heavily modified by Ulrich Drepper to fit in the
1509 NSS scheme used in glibc.
1511 * There is a new malloc debugging hook `__memalign_hook'.
1513 * There are new typedefs `ushort' for `unsigned short int' and `uint' for
1514 `unsigned int' in <sys/types.h>. These are for compatibility only and
1515 their use is discouraged.
1517 * The `-lmcheck' library to enable standard malloc debugging hooks is now
1518 done differently, so that it works even without GNU ld.
1520 * New function `euidaccess' checks allowed access to a file like `access',
1521 but using the effective IDs instead of the real IDs.
1523 * The time zone data files have been updated for the latest and greatest
1524 local time conventions of the countries of the world.
1526 * The new function `dirfd' extracts the file descriptor used by a DIR stream;
1529 * The new functions `ecvt', `fcvt', and `gcvt' provide an obsolete interface
1530 for formatting floating-point numbers. They are provided only for
1531 compatibility; new programs should use `sprintf' instead. There are
1532 also equivalent function for the `long double' floating-point type and
1533 all functions also exist in a reentrant form.
1535 * The new auxiliary library `-lutil' from 4.4 BSD contains various
1536 functions for maintaining the login-record files (primarily of use to
1537 system programs such as `login'), and convenient functions for
1538 allocating and initializing a pseudo-terminal (pty) device.
1540 * Ulrich Drepper has contributed new support for System V style
1541 shared memory and IPC on systems that support it.
1543 * Ulrich Drepper has contributed several miscellaneous new functions found
1544 in System V: The `hsearch' family of functions provide an effective
1545 implementation of hash tables; `a64l' and `l64a' provide a very simple
1546 binary to ASCII mapping; `drand48' and friends provide a 48-bit random
1549 * Ulrich Drepper has contributed new reentrant counterparts for the
1550 `random' and `hsearch' families of functions; `random_r', `hsearch_r', etc.
1552 * Ulrich Drepper has contributed new, highly-optimized versions of several
1553 string functions for the i486/Pentium family of processors.
1555 * Ulrich Drepper has updated the Linux-specific code, based largely
1556 on work done in Hongjiu Lu's version of GNU libc for Linux.
1557 The GNU library now supports Linux versions 2.0.10 and later,
1558 using the ELF object file format (i[3456]86-*-linux).
1560 * Andreas Schwab has ported the C library to Linux/m68k (m68k-*-linux).
1562 * David Mosberger-Tang and Richard Henderson have ported the C library
1563 to Linux/Alpha (alpha-*-linux). Richard Henderson contributed the
1564 dynamic linking support for ELF/Alpha.
1566 * Richard Henderson contributed several Alpha optimized assembler function
1567 for arithmetic and string handling.
1569 * Ulrich Drepper has contributed a new set of message catalog functions to
1570 support multiple languages using the <libintl.h> interface, for use with
1571 his new package GNU gettext. Translation volunteers have contributed
1572 catalogs of the library's messages in Spanish, German, and Korean.
1574 * For compatibility with XPG4, Ulrich Drepper has contributed the `gencat'
1575 program and the `catgets' function for reading the catalog files it
1576 creates. (The <libintl.h> interface is preferred; we include the
1577 <nl_types.h> interface using `catgets' only for source compatibility with
1578 programs already written to use it.)
1580 * New header file <values.h> gives SVID-compatible names for <limits.h>
1583 * Various new macros, declarations, and small header files for compatibility
1586 * New function `group_member' is a convenient way to check if a process has
1587 a given effective group ID.
1589 * When using GCC 2.7 and later, the socket functions are now declared in a
1590 special way so that passing an argument of type `struct sockaddr_in *',
1591 `struct sockaddr_ns *', or `struct sockaddr_un *' instead of the generic
1592 `struct sockaddr *' type, does not generate a type-clash warning.
1594 * New function `error' declared in header file <error.h> is a convenient
1595 function for printing error messages and optionally exiting; this is the
1596 canonical function used in GNU programs. The new functions `err', `warn',
1597 and friends in header file <err.h> are the canonical 4.4 BSD interface for
1598 doing the same thing.
1600 * The <glob.h> interface has several new flags from 4.4 BSD that extend the
1601 POSIX.2 `glob' function to do ~ and {...} expansion.
1603 * New function `unsetenv' complements `setenv' for compatibility with 4.4 BSD.
1604 `clearenv' which is used in POSIX.9 is also available.
1606 * New function `getsid' returns session ID number on systems that support it.
1608 * We have incorporated the 4.4 BSD `db' library (version 1.85). New header
1609 files <db.h> and <mpool.h> provide a rich set of functions for several
1610 types of simple databases stored in memory and in files, and <ndbm.h> is
1611 an old `ndbm'-compatible interface using the `db' functions. Link with
1612 `-ldb' to get these functions.
1614 * New macro `strdupa' copies a string like `strdup', but uses local stack
1615 space from `alloca' instead of dynamic heap space from `malloc'.
1617 * New function `strnlen' is like `strlen' but searches only a given maximum
1618 number of characters for the null terminator. `stpncpy', `strndup' and
1619 `strndupa' are similar variants for the `stpcpy', `strdup' and `strdupa'
1622 * New function `statfs' in header <sys/statfs.h>.
1624 * The new <argz.h> and <envz.h> interfaces contributed by Miles Bader
1625 provide convenient functions for operating on blocks of null-terminated
1628 * A new suite of functions in <utmp.h> handle all the details of reading
1629 and writing the utmp file.
1631 * An implementation of the NIS/YP(tm) based NSS service was contributed by
1634 * Paul Eggert and Ulrich Drepper modified the `strftime' function to be
1635 completely POSIX compliant and also implemented the extended functionality
1636 to handle alternate digit representation and alternate era date formats.
1638 * Ulrich Drepper provided an implementation of the `strptime' function
1639 defined in XPG4.2 which transforms a string into a `struct tm' value.
1641 * Paul Eggert provided the tzselect shell script as part of the timezone
1642 code. The shell script makes it easy to select the correct timezone
1645 * The implementation of the malloc family of functions is completely replaced
1646 by a new implementation by Doug Lea with many improvements by Wolfram Gloger.
1647 The implementation uses the mmap function (if available) and it is
1648 optimized for the use in multi threaded programs.
1650 * Ulrich Drepper contributed a MD5 "encryption" for the crypt family of
1651 functions. This new functionality is usable by specifying a special
1652 salt string and it is compatible with implementation on *BSD systems.
1654 * Lots of functions from the XPG4.2 standard were added by Ulrich Drepper:
1655 `getsubopt' to handle second level command line options, `bsd_signal'
1656 to access BSD style `signal' functionality, the obsolete `regexp' style
1659 * the `lchown' function is available on system which support this
1662 * The implementation of the shadow password handling function was contributed
1665 * David Mosberger-Tang changed the SunRPC implementation to be 64bit safe.
1667 * POSIX.1g support was added. The <sys/select.h> header is available,
1668 `isfdtype' and `pselect' are implemented. Craig Metz contributed an
1669 implementation of `getaddrinfo'.
1673 * For cross-compilation you should now set `BUILD_CC' instead of `HOST_CC'.
1675 * New header file <fstab.h> and new functions `getfsspec', `getfsent' and
1676 friends, for parsing /etc/fstab. This code comes from 4.4 BSD.
1678 * The new function `daemon' from 4.4 BSD is useful for server programs that
1679 want to put themselves in the background.
1681 * Joel Sherrill has contributed support for several standalone boards that
1682 run without an operating system.
1684 * `printf', `scanf' and friends now accept a `q' type modifier for long
1685 long int as well as `ll'. Formats using these might be `%qu' or `%lld'.
1687 * All of the code taken from BSD (notably most of the math and networking
1688 routines) has been updated from the BSD 4.4-Lite release.
1690 * The resolver code has been updated from the BIND-4.9.3-BETA9 release.
1692 * The new functions `getdomainname' and `setdomainname' fetch or change the
1693 YP/NIS domain name. These are system calls which exist on systems which
1696 * The time zone data files have been updated for the latest international
1699 * The SunRPC programs `portmap' and `rpcinfo' are now installed in
1700 $(sbindir) (usually /usr/local/sbin) instead of $(bindir).
1704 * The C library now includes support for Sun RPC, from Sun's free
1705 RPCSRC-4.0 distribution. The `portmap', `rpcinfo', and `rpcgen' programs
1706 are included. (There is still no support for YP.)
1708 * Tom Quinn has contributed a port of the C library to SGI machines running
1709 Irix 4 (mips-sgi-irix4).
1711 * The new `lockf' function is a simplified interface to the locking
1712 facilities of `fcntl', included for compatibility.
1714 * New time functions `timegm', `timelocal', and `dysize' for compatibility.
1716 * New header file <sys/timeb.h> and new function `ftime' for compatibility.
1718 * New header files <poll.h> and <sys/poll.h> and new function `poll' for
1721 * The error message printed by `assert' for a failed assertion now includes
1722 the name of the program (if using GNU ld) and the name of the calling
1723 function (with versions of GCC that support this).
1725 * The `psignal' function is now declared in <signal.h>, not <stdio.h>.
1727 * The library now includes the <sys/mman.h> header file and memory
1728 management functions `mmap', `munmap', `mprotect', `msync', and
1729 `madvise', on systems that support those facilities.
1731 * The interface for `mcheck' has changed slightly: the function called to
1732 abort the program when an allocation inconsistency is detected now takes
1733 an argument that indicates the type of failure. The new function
1734 `mprobe' lets you request a consistency check for a particular block at
1735 any time (checks are normally done only when you call `free' or `realloc'
1738 * It is now possible to easily cross-compile the C library, building on one
1739 system a library to run on another machine and/or operating system. All
1740 you need to do is set the variable `HOST_CC' in `configparms' to the
1741 native compiler for programs to run on the machine you are building on (a
1742 few generator programs are used on Unix systems); set `CC' to the
1745 * The new function `fexecve' (only implemented on the GNU system) executes
1746 a program file given a file descriptor already open on the file.
1750 * Brendan Kehoe has contributed most of a port to the DEC Alpha
1751 running OSF/1 (alpha-dec-osf1). He says it is 75% complete.
1753 * You can set the variable `libprefix' in `configparms' to specify a prefix
1754 to be prepended to installed library files; this makes it easy to install
1755 the GNU C library to be linked as `-lgnuc' or whatever.
1757 * The new `stpncpy' is a cross between `stpcpy' and `strncpy': It
1758 copies a limited number of characters from a string, and returns the
1759 address of the last character written.
1761 * You no longer need to check for whether the installed `stddef.h' is
1762 compatible with the GNU C library. configure now checks for you.
1764 * You can now define a per-stream `fileno' function to convert the
1765 stream's cookie into an integral file descriptor.
1767 * ``malloc (0)'' no longer returns a null pointer. Instead, it
1768 allocates zero bytes of storage, and returns a unique pointer which
1769 you can pass to `realloc' or `free'. The behavior is undefined if
1770 you dereference this pointer.
1772 * The C library now runs on Sony NEWS m68k machines running either
1773 NewsOS 3 or NewsOS 4.
1775 * The new `syscall' function is a system-dependent primitive function
1776 for invoking system calls. It has the canonical behavior on Unix
1777 systems, including unreliable return values for some calls (such as
1778 `pipe', `fork' and `getppid').
1780 * The error code `EWOULDBLOCK' is now obsolete; it is always defined
1781 to `EAGAIN', which is the preferred name. On systems whose kernels
1782 use two distinct codes, the C library now translates EWOULDBLOCK to
1783 EAGAIN in every system call function.
1787 * The GNU C Library Reference Manual is now distributed with the library.
1788 `make dvi' will produce a DVI file of the printed manual.
1789 `make info' will produce Info files that you can read on line using C-h i
1790 in Emacs or the `info' program.
1791 Please send comments on the manual to bug-glibc-manual@gnu.org.
1793 * The library now supports SVR4 on i386s (i386-unknown-sysv4).
1795 * Brendan Kehoe has contributed a port to Sun SPARCs running Solaris 2.
1797 * Jason Merrill has contributed a port to the Sequent Symmetry running
1798 Dynix version 3 (i386-sequent-dynix).
1800 * The library has been ported to i386s running SCO 3.2.4 (also known as SCO
1801 ODT 2.0; i386-unknown-sco3.2.4) or SCO 3.2 (i386-unknown-sco3.2).
1803 * New function `memory_warnings' lets you arrange to get warnings when
1804 malloc is running out of memory to allocate, like Emacs gives you.
1806 * The C library now contains the relocating allocator used in Emacs 19 for
1807 its editing buffers. This allocator (ralloc) minimizes allocation
1808 overhead and fragmentation by moving allocated regions around whenever it
1809 needs to. You always refer to a ralloc'd region with a "handle" (a
1810 pointer to a pointer--an object of type `void **').
1812 * There is a new `printf' format: `%m' gives you the string corresponding
1813 to the error code in `errno'.
1815 * In `scanf' formats, you can now use `%as' or `%a[' to do the normal `%s'
1816 or `%[' conversion, but instead of filling in a fixed-sized buffer you
1817 pass, the `a' modifier says to fill in a `char **' you pass with a
1820 * The `fnmatch' function supports the new flag bits `FNM_LEADING_DIR' and
1821 `FNM_CASEFOLD'. `FNM_LEADING_DIR' lets a pattern like `foo*' match a
1822 name like `foo/bar'. `FNM_CASEFOLD' says to ignore case in matching.
1824 * `mkstemp' is a traditional Unix function to atomically create and open a
1825 uniquely-named temporary file.
1829 * The standard location for the file that says what the local timezone is
1830 has changed again. It is now `/usr/local/etc/localtime' (or more
1831 precisely, `${prefix}/etc/localtime') rather than `/etc/localtime'.
1833 * The distribution no longer contains any files with names longer than 14
1836 * `struct ttyent' has two new flag bits: TTY_TRUSTED and TTY_CONSOLE.
1837 These are set by the new `trusted' and `console' keywords in `/etc/ttys'.
1839 * New functions `ttyslot' and `syslog' from 4.4 BSD.
1843 * The configuration process has changed quite a bit. The `configure'
1844 script is now used just like the configuration scripts for other GNU
1845 packages. The `sysdeps' directory hierarchy is much rearranged.
1846 The file `INSTALL' explains the new scheme in detail.
1848 * The header files no longer need to be processed into ANSI C and
1849 traditional C versions. There is just one set of files to install, and
1850 it will work with ANSI or old C compilers (including `gcc -traditional').
1852 * Brendan Kehoe and Ian Lance Taylor have ported the library to the
1853 MIPS DECStation running Ultrix 4.
1855 * The Sun 4 startup code (crt0) can now properly load SunOS 4 shared libraries.
1856 Tom Quinn contributed the initial code. The GNU C library can NOT yet be
1857 made itself into a shared library.
1859 * Yet further improved support for the i386, running 4.3 BSD-like systems
1860 (such as Mach 3 with the Unix single-server), or System V.
1862 * New function `strncasecmp' to do case-insensitive string comparison
1863 with limited length.
1865 * New function `strsep' is a reentrant alternative to `strtok'.
1867 * New functions `scandir' and `alphasort' for searching directories.
1869 * New function `setenv' is a better interface to `putenv'.
1871 * Ian Lance Taylor has contributed an implementation of the SVID `ftw'
1872 function for traversing a directory tree.
1874 * The GNU obstack package is now also part of the C library.
1875 The new function `open_obstack_stream' creates a stdio stream that
1876 writes onto an obstack; `obstack_printf' and `obstack_vprintf' do
1877 formatted output directly to an obstack.
1879 * Miscellaneous new functions: reboot, nice, sigaltstack (4.4 BSD only),
1880 cfmakeraw, getusershell, getpass, swab, getttyent, seteuid, setegid.
1882 * `FNM_FILE_NAME' is another name for `FNM_PATHNAME', used with `fnmatch'.
1884 * The new functions `strfry' and `memfrob' do mysterious and wonderful
1885 things to your strings.
1887 * There are some new test programs: test-fseek, testmb, and testrand.
1889 * Some work has been done to begin porting the library to 4.4 BSD and Linux.
1890 These ports are not finished, but are a good starting place for really
1891 supporting those systems.
1893 * `/etc/localtime' is now the standard location for the file that says what
1894 the local timezone is, rather than `/usr/local/lib/zoneinfo/localtime'.
1895 This follows the general principle that `/etc' is the place for all local
1896 configuration files.
1898 * The C library header files now use `extern "C"' when used by the C++
1899 compiler, so the C library should now work with C++ code.
1901 * The header file <bstring.h> is gone. <string.h> now declares bcopy,
1902 bcmp, bzero, and ffs. (Update: nowadays these functions are declared
1905 * Mike Haertel (of GNU e?grep and malloc fame) has written a new sorting
1906 function which uses the `merge sort' algorithm, and is said to be
1907 significantly faster than the old GNU `qsort' function. Merge sort is
1908 now the standard `qsort' function. The new algorithm can require a lot
1909 of temporary storage; so, the old sorting function is called when the
1910 required storage is not available.
1912 * The C library now includes Michael Glad's Ultra Fast Crypt, which
1913 provides the Unix `crypt' function, plus some other entry points.
1915 * The code and header files taken from 4.4 BSD have been updated with the
1916 latest files released from Berkeley.
