What I wanted to say is that we preserve the function type used for
the actual call at least until RTL expansion in gimple_call_fntype.
I fixed most of the call expansion code to honor that but back ends
may of course screw up as they still may somehow get at the actual
DECL called.

I think that's a good thing -- however, I suspect there's m68k backendissues that need to be addressed here. So I think we're roughly on thesame page.
