From a379e56acc0955dd1ec03740cfbb632ce54b7416 Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Wed, 23 Sep 1998 15:28:54 +0000 Subject: Update. 1998-09-23 15:25 Ulrich Drepper * 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.
