From 195bcbf5078d74c8e00d68f04eb8695196fb31e8 Mon Sep 17 00:00:00 2001 From: Josh Boyer <jwboyer@redhat.com> Date: Thu, 18 Aug 2011 07:37:21 -0400 Subject: [PATCH] perf tools: Fix build against newer glibc Upstream glibc commit 295e904 added a definition for __attribute_const__ to cdefs.h. This causes the following error when building perf: util/include/linux/compiler.h:8:0: error: "__attribute_const__" redefined [-Werror] /usr/include/sys/cdefs.h:226:0: note: this is the location of the previous definition Wrap __attribute_const__ in #ifndef as we do for __always_inline.
