Apply patch for C standards compliance:

Apply patch for C standards compliance:
	"All declarations that
	refer to the same object or function shall have compatible type;
	otherwise, the behavior is undefined."  (That's from ISO/IEC 9899:TC2
	final committee draft, section 6.2.7.)

	This doesn't trigger issues with most C implementations, but there
	is one implementation in development (GCC LTO branch) which does
	flag this issue.
