Update.
2001-02-07 Ulrich Drepper <drepper@redhat.com> * sysdeps/gnu/netinet/tcp.h: Correct values of TCP_ macros. Patch by Pekka.Pietikainen@cern.ch. * posix/regex.c: Correct several problems with 64-bit architectures introduced in the MBS changes. Patch by Isamu Hasegawa <isamu@yamato.ibm.com>. 2001-02-07 Jakub Jelinek <jakub@redhat.com> * math/tgmath.h: Only add l suffixes if __NO_LONG_DOUBLE_MATH is not defined. * sysdeps/alpha/fpu/bits/mathinline.h: Honour __NO_MATH_INLINES.
