This is ok.

Can't test these generically.

What's the point of this test case, anyway?  Seems to me that
we should be doing functionality tests for each of these
attributes, which tests parsing at the same time.

For instance, this patch should be accompanied by a C++ test like

	// { dg-do link }
	extern void foo() __attribute__((nothrow))
	extern void link_error();
	int main()
	  try {
	  } catch (...) {
	void foo() { }

which should fail before your patch and pass afterward.
