Update.
1998-07-23  Ulrich Drepper  <drepper@cygnus.com>

	* sysdeps/generic/glob.c: Fix two problems with GLOB_DOOFFS.
	Reported by bwelling@anomaly.munge.com [PR libc/720].

	* sysdeps/libm-ieee754/k_standard.c: Return NAN for libm not in
	SVID more for gamma(x) with x interger <= 0.
	Reported by Stephen L Moshier <moshier@mediaone.net>.

	* math/libm-test.c (gamma_test): Add test for gamma(-1) and gamma(0).
	Correct test for SVID version of gamma.

	* sysdeps/libm-ieee754/w_gamma.c: Use correct matherr call in SVID
	emulation mode.
	* sysdeps/libm-ieee754/w_gammaf.c: Likewise.
	* sysdeps/libm-ieee754/w_gammal.c: Likewise.

	* string/string.h: Don't use string function optimization for C++
	as long as we use macros.
