This code works everywhere except on my MIPS machine:

typedef enum Foo {
	None=0,
	Some,
	All
} Foo;

main() {
	Foo x, y;

	x = (None<<2)|Some;

	switch (x) {
	case (((unsigned)None)<<2)|(((unsigned)Some)):
			printf( "blah\n" );
			break;
	}
}

MIPS cc says:
ccom: Error: enum.c, line 13: non-constant case expression
	case (((unsigned)None)<<2)|(((unsigned)Some)):
