You need a configure check.  e.g. 4.4 supports __attribute__ ((optimize))
but doesn't grok that particular option, so it says:
	o.c:2: error: unrecognized command line option "-fno-tree-loop-distribute-patterns"
for:
	__attribute__ ((optimize ("no-tree-loop-distribute-patterns")))
	void foo (void) {}
