Yes it seems odd.  The fix I installed considers only the first unspecified
parameter DIE.  After that one, no other DIE is considered as being function
parameters.

I hope this would be enough of a fix for now.

Yeah, that is weird.  But, as always, if we can find a way to handle the
binaries that are already out there in the wild -- before the compiler gets
fixed -- we just use that way.
