This improves the diagnostics messages in case we're using initial
declarations in the for loop, but we're not using C99 or newer standard;
in this case we shouldn't forget about =c11 and =gnu11, where the
initial declaration is fine as well.

Ok for trunk?

	PR c/57630
	* c-decl.c (check_for_loop_decls): Improve diagnostics messages.
