Update.
1998-08-03 16:36 Ulrich Drepper <drepper@cygnus.com>
* catgets/catgets.c: Use mmap/munmap only is _POSIX_MAPPED_FILES
is defined.
* catgets/open_catalog.c: Likewise.
* iconv/iconv_prog.c: Likewise.
* intl/loadmsgcat.c: Likewise.
* locale/findlocale.c: Likewise.
* locale/loadlocale.c: Likewise.
* locale/programs/localedef.c: Likewise.
* malloc/malloc.c: Likewise.
* elf/elf.h: Fix typo.

1998-08-01 02:49 -0400 Zack Weinberg <zack@rabi.phys.columbia.edu>
* sysdeps/posix/tempname.c (__stdio_gen_tempname): Rename to
__gen_tempname and simplify the interface. Strip out the
code to do path search and create FILE objects. This function
now takes a mktemp() style template and returns either a name
or a file descriptor.
(__path_search): New function; searches for directories for
temp files.
* sysdeps/generic/tempname.c: Stub out __gen_tempname and
__path_search, not __stdio_gen_tempname.
* libio/stdio.h: Prototype __gen_tempname and __path_search,
not __stdio_gen_tempname.
* stdio/stdio.h: Likewise.
* stdio-common/tempnam.c: Use __path_search and __gen_tempname.
* stdio-common/tmpfile.c: Likewise.
* stdio-common/tmpfile64.c: Likewise.
* stdio-common/tmpnam.c: Likewise.
* stdio-common/tmpnam_r.c: Likewise.
* misc/mkstemp.c: New file. Use __gen_tempname.
* misc/mktemp.c: Likewise.
* sysdeps/posix/mkstemp.c: Removed.
* sysdeps/posix/mktemp.c: Removed.
* sysdeps/generic/mkstemp.c: Removed.
* sysdeps/generic/mktemp.c: Removed.
1998-08-02 Thorsten Kukuk <kukuk@vt.uni-paderborn.de>
* configure.in: Check, if door add-on is installed.
* config.make.in: Add have_doors.
* sunrpc/Makefile: Add HAVE_DOOR define.
* sunrpc/key_call.c: Add keyserv/door interface.
* sunrpc/svc_unix.c: Call setsockopt only if SO_PASSCRED is defined.
* sunrpc/clnt_unix.c: Likewise.
1998-08-02 Andreas Jaeger <aj@arthur.rhein-neckar.de>
* inet/netinet/in.h (IN_CLASSC): Correct mask.
Reported by Ian Staniforth <I.Staniforth@sheffield.ac.uk> [fixes
PR libc/727].
1998-08-03 10:23 Ulrich Drepper <drepper@cygnus.com>
* misc/Makefile: Fix installation problem with --disable-shared.
* posix/Makefile: Likewise.
1998-08-02 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* posix/regex.c (re_search_2): Optimize searching for anchored
pattern if '^' cannot match at embedded newlines.
(regerror): Renamed from __regerror, which it should only be
called if _LIBC.
1998-07-31 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sunrpc/svc_unix.c (__msgread): Check setsockopt return value.
1998-07-31 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* sysdeps/generic/glob.c: Remove obsolete cast.
1998-07-31 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* Rules (tests): Fix last change.
