I completely agree with you, but I was worried about another case.

I'm wondering if a particular linker implementation must declare its compatibility with the C calling convention for that platform? An implementation may reject many things that are possible, but what it accepts _must_ be consistent with the native convention, otherwise it doesn't make sense.
