I don't think you really need to assemble this. s/object/assembly/
would do. Even preprocessing alone would do, but I don't think
check_compiler can do that.

That doesn't matter for this test of course, but making things more tricky for no win is a bad tradeoff. Also, I didn't even bother to consider not assembling it :-) Segher
