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.
