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.

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.
