re PR other/51011 (FAIL: gcc.dg/atomic-generic.c (test for excess errors))

2011-11-24  Andrew MacLeod  <amacleod@redhat.com>

	PR other/51011
	* tree.h (is_builtin_name): No longer external.
	* builtins.c (is_builtin_name): Make static.
	* varasm.c (incorporeal_function_p): __sync and __atomic external calls
	are not incorporeal and may need asm label processing.
