Okay, so we have to keep that in mind for the future. Do the arguments
to the __has_feature() macro change accordingly? For now, I modified
gnustep-make to also check for the compiler default. This should get rid
of any unexpected mismatch, though we still might want an option to
disable it explicitly.
