Update.

1999-09-10  Ulrich Drepper  <drepper@cygnus.com>

	* wcsmbs/wchar.h (WCHAR_MIN, WCHAR_MAX): Use all-numeric values.

	* sysdeps/generic/stdint.h: Correct WCHAR_MIN, WCHAR_MAX, and
	WINT_MAX values.

	* wctype/wctype.h: Remove incorrect towlower/towupper optimizations.

1999-09-09  Andreas Schwab  <schwab@suse.de>

	* elf/link.h: Fix comment.

1999-09-10  Ulrich Drepper  <drepper@cygnus.com>

	* math/bits/mathcalls.h: Add __isnan declaration [PR libc/1294].

	* math/math.h: Pretty print.
