Ulrich Drepper 3499233817 Update.
1999-01-07  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/i386/bits/select.h (__FD_ZERO): Remove early clobbers
	from c and D register output.

1999-01-07  Philip Blundell  <philb@gnu.org>

	* sysdeps/unix/sysv/linux/arm/sigcontextinfo.h: Fix bug in last change.

1999-01-07  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/unix/sysv/linux/alpha/bits/types.h: Correct type for
	__fsfilcnt_t.  Patch by Bruce Elliott <bde@nwlink.com>.

1999-01-05  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* manual/conf.texi: Remove pointers from first @node.  Move old
	@node spec inside comment.
	* manual/lang.texi: Likewise.
	* manual/libc-texinfo.sh: Also find `@node.*Top' in a comment.
	* manual/stdio.texi: Fix typo.

1999-01-04  Andreas Schwab  <schwab@issan.cs.uni-dortmund.de>

	* wcsmbs/btowc.c: Accept all values in the range [SCHAR_MIN
	.. UCHAR_MAX].  Local var buf renamed to result and its type
	changed from char[] to wchar_t to get proper alignment.

	* posix/fnmatch.c: Also cast the arguments of the other ctype
	functions to unsigned char.

1999-01-07  Ulrich Drepper  <drepper@cygnus.com>

	* Rules: Add rules for empty.{o,os,op} back.
