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.
