Update.
1998-11-16 Ulrich Drepper <drepper@cygnus.com>
* sysdeps/unix/opendir.c: Use o_directory_works differently. Treat
zero value as uninitialized so that variable can go into .bss.
* dirent/opendir-tst1.c: Print error strings to stdout.
* sysdeps/unix/sysv/linux/mmap64.c: New file. Empty.
* sysdeps/unix/sysv/linux/syscalls.list: Add mmap with mmap64 alias.
* sysdeps/unix/sysv/linux/arm/mmap.S: Add mmap64 alias.
* sysdeps/unix/sysv/linux/i386/mmap.S: Likewise.
* sysdeps/unix/sysv/linux/m68k/mmap.S: Likewise.
1998-11-16 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
* time/tzfile.c (__tzfile_read): Check that types[i].isdst is in
range.
1998-11-16 Ulrich Drepper <drepper@cygnus.com>
* libio/bits/stdio.h (fread_unlocked): Do handle zero size and number.
(fwrite_unlocked): Likewise.
1998-11-16 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
* libio/bits/stdio.h (fread_unlocked): Don't evaluate non-constant
twice. Don't bother handling zero size.
(frwite_unlocked): Likewise.
1998-11-15 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
* configure.in: Fix regex for makeinfo version string.
1998-11-15 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
* sunrpc/rpc_sample.c (write_sample_server): Avoid -Wparentheses
warning.
* sunrpc/rpc_svcout.c (write_program): Likewise.
1998-11-15 Andreas Schwab <schwab@issan.cs.uni-dortmund.de>
* time/Makefile (CFLAGS-test_time.c): Add -Wno-format.
1998-11-16 Ulrich Drepper <drepper@cygnus.com
* misc/sys/mman.h: Pretty print prototypes.
1998-11-15 Ulrich Drepper <drepper@cygnus.com
* misc/error.c (error): Don't use result of strerror_r call directly
since at least DEC Unix has a wrong return type.
Patch by Johan Danielsson <joda@pdc.kth.se>.
