Created attachment 22255
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=22255
gcc46-pr46234.patch

Untested fix.  Could anyone please bootstrap/regtest this on ppc and s390?  It
might take a while before I'd manage to do that myself.

Bootstrap/regtest went fine on PPC, va-arg-xxx tests now pass.
