From 266865c0e7b79d4196e2cc393693463f03c90bd8 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Tue, 2 Dec 2014 21:32:48 +0000 Subject: [PATCH] Remove excess declarations from unistd.h for XPG3/XPG4 (bug 17665). For XPG3/XPG4 (defined __USE_XOPEN && !defined __USE_UNIX98), unistd.h declares many functions that should only be declared for __USE_MISC (none of them are in XPG3/XPG4): sethostname sethostid getdomainname setdomainname vhangup revoke profil acct getusershell endusershell setusershell daemon. The whole block with the [__USE_MISC || (__USE_XOPEN && !__USE_UNIX98)] conditional contains only functions that are not in XPG3/XPG4, so this patch simply changes the conditional. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by this patch).
