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.
