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>.
