I don't have a patch.  I'm not sure why DJ thinks I have one.

The assembly output for stdcall functions is "interesting" now.  A
caller of a stdcall function apparently knows that the stdcall function
might pop too many things off the stack and fixes things up
appropriately.  That's interesting but it certainly isn't the correct
semantics for stdcall.
