From b9eca49e378d183ddf418f5deae1f389cd31dc28 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 10 May 2016 14:56:49 +0000 Subject: Declare cuserid in unistd.h for UNIX98 and before (bug 20043). For UNIX98 and older X/Open standards, unistd.h should have a declaration of the legacy cuserid function, but such a declaration is missing. This patch adds that missing declaration. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch).
