Update.
1998-09-23 15:25 Ulrich Drepper <drepper@cygnus.com> * libio/stdio.h: Define __need_getopt and include getopt.h to define getopt stuff. * posix/unistd.h: Likewise. * stdio/stdio.h: Likewise. * posix/getopt.h: Remove _GNU_SOURCE use. If __need_getopt is defined define only getopt and the variables. (CPPFLAGS): Add -DUSE_LIBDB1
