        using length word.

        * stdio/internals.c (__stdio_check_offset): Call init_stream to make
        sure we have fns.

        * stdio/fread.c: Don't call __fillbf if the put_limit is past the
        beginning of the buffer; only if !seen, no buffer, or pushed back.

        * stdio/fopen.c (__getmode): Set create bit for "a" mode.

        * io/mkdir.c: #undef mkdir before fn alias.

        * time/tzfile.c (__tzfile_compute): Don't decrement I if it's zero.

        year, not every 1000th.

        * stdio/internals.c (flushbuf): Increment the target position the
        amount the user wrote into the buffer, not the amount we wrote out

        in the middle).

        * stdio/internals.c (flushbuf): Set get_limit to the beginning of
        the buffer for all streams, except when we have just read in a block.

        Use CTR register for looping (speed enhancement).  Don't emit

        macro).
        * sysdeps/rs6000/memcopy.h (WORD_COPY_BWD):

        saving fp regs.

        * Renamed oodles of files, changed all the relevant Makefiles (I

        * grp/initgroups.c: Removed redundant test.

        without depending on make vars that might not be right yet.

Mon Feb 10 00:55:58 1992  Roland McGrath  (roland@churchy.gnu.ai.mit.edu)

        * stdlib/stdlib.h: #undef alloca before declaring it.

        * sysdeps/sparc/__longjmp.S: Use be instead of bz.

        * sysdeps/unix/bsd/Dist: Add bsdtty.h.

        * tzfile.c (__tzfile_read): Don't allocate space for 0 leaps.
        Don't loop infinitely.

        * sysdeps/unix/Makefile (make-errnos.c): Use tr to eat newlines in

        * sysdeps/unix/bsd/sun/sun4/__brk.S: Fix andn arg order.

        * posix/Makefile: Don't get getopt by vpath.  Turns out to be too
        much hassle for dist.  Just made symlinks in posix/ instead.

        * manual/Makefile: Renamed summary.out to summary.texinfo.

        * manual/summary.awk: New file, to make summary.out.
        Replaces `process-definitions.el'.
        * manual/Makefile (summary.out): Create using summary.awk.

        * manual/Makefile: Created.
        * Makefile, Make-dist: Use it to format and distribute the manual.

Mon Feb 10 00:32:17 1992  Jim Meyering  (meyering@churchy.gnu.ai.mit.edu)

        * All Makefiles:
        Whenever using shell redirection to create a target,
        do not create the target directly like this

            foo: bar
                    process $< > $@

        That loses when `process' fails (interrupt, disk full, ...)
        and bar exists and looks up-to-date, but isn't.
        This sort of failure is particularly insidious when
        the initial error message is obscured by lots of subsequent
        output (echoed commands etc).

        Instead use rules like this

            foo: bar
                    process $< > $@-tmp
                    mv $@-tmp $@

        Using this paradigm, as long as process returns non-zero
        whenever it fails, the target won't be touched.

        * configure: Create config.status to set ARCH, if successful.
        * Makeconfig: include config.status ifndef ARCH.

        68881 file.  HUGE_VAL redone to be machine independent.
        (NAN): New macro for an IEEE NaN, done like HUGE_VAL.
        * sysdeps/m68k/68881/fl.h: Now #includes ieee754/fl.h, and overrides
        FLT_ROUNDS for 68881 magic.  NB: the #include is a prob. for install.

Wed Jan 29 17:11:25 1992  Roland McGrath  (roland@albert.gnu.ai.mit.edu)

        * sysdeps/posix/getcwd.c: Don't use chdir; use a long ../../../...

        * posix/Makefile (headers): Added getopt.h.

        * termios/speed.c, sysdeps/unix/bsd/{__tcgetattr,tcsetattr}.c: Store
        speeds as their own values (B9600==9600, etc.) and translate to BSD
        values only for ioctl.
        * termios/cfsetpseed.c: New fn to set both speeds at once (from 4.4).

        * sysdeps/generic/uname.c (uname): Save and restore errno if

        * stdio/perror.c (perror): Check correctly for S == "".
        Check correctly for ERRNUM being in range.

        * find-sysdirs: Don't use fgrep -s, since USG apparently doesn't
        have that flag.  Just >/dev/null instead.

Mon Jan 13 17:00:15 1992  Torbjorn Granlund  (tege at mole.gnu.ai.mit.edu)

        * sysdeps/generic/wordcopy.c (all four functions): Move do0 label to
        the ultimate store statement at the end of each function.  (Used to

        * resource/sys/resource.h (struct rusage): Change `ru_outblock' to
