Ulrich Drepper 310b3460e0 Update.
1998-04-14 16:34  Ulrich Drepper  <drepper@cygnus.com>

	* test-skeleton.c: Provide hook for initializing code before the fork.
	* rt/tst-aio.c: Use PREPARE hook to make suer temp files are always
	removed.

	* libio/fcloseall.c (__fcloseall): Return return value of _IO_cleanup.
	* libio/genops.c (_IO_cleanup): Return return value of _IO_flush_all.
	* libio/libioP.h: Adopt _IO_cleanup prototype.

	* stdlib/Makefile (tests): Add test-canon2.
	* stdlib/test-canon2.c: New file.
	* stdlib/canonicalize.c (canonicalize): Allow RESOLVED parameter to
	be NULL.  Use __lxstat, not __lstat.  Correctly recognize long
	symlink sequences.
	(__realpath): Make real function which checks RESOLVED parameter for
	not being NULL.

1998-04-14  Ulrich Drepper  <drepper@cygnus.com>

	* catgets/open_catalog.c (__open_catalog): Fix problems with
	reading non-files.  Always close file.
	Reported by Cristian Gafton <gafton@redhat.com>.

	* elf/dl-minimal.c (__strtol_internal): Prevent overflow warnings.

1998-04-14 13:28  Ulrich Drepper  <drepper@cygnus.com>

	* libc.map: Add various low-level I/O functions.

1998-04-14 10:35  Ulrich Drepper  <drepper@cygnus.com>

	* string/Makefile (routines): Remove strerror_r.
	* string/strerror_r.c: Removed.
	* string/strerror.c: Call __strerror_r for doing the real work.
	* sysdeps/generic/_strerror.c: Rename function to __strerror_r and
	add weak alias strerror_r.
	* sysdeps/mach/_strerror.c: Likewise.
	* assert/assert-perr.c: Use __strerror_r instead of _strerror_internal.
	* elf/dl-error.c (_dl_signal_error): Likewise.
	* elf/dl-profile.c (_dl_start_profile): Likewise.
	* gmon/gmon.c (write_gmon): Likewise.
	* stdio-common/perror.c: Likewise.
	* stdio-common/vfprintf.c: Likewise.

1998-04-10  Mark Kettenis  <kettenis@phys.uva.nl>

	* sysdeps/unix/sysv/linux/Makefile [$(subdir)=inet]
	(sysdep_headers): Add netatalk/at.h.

1998-04-12  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* manual/socket.texi, manual/creature.texi, manual/time.texi:
	Formatting fixes.

1998-04-13  Andreas Schwab  <schwab@issan.informatik.uni-dortmund.de>

	* posix/regex.c: Rename __re_syntax_options back to
	re_syntax_options, aliases do not work with global variables due
	to copy relocations.
	(regex_compile): Use syntax parameter instead of
	re_syntax_options.

1998-04-14  Andreas Jaeger  <aj@arthur.rhein-neckar.de>

	* configure.in: Document that enable-force-install is default.
