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.
