is is a problem with gcc's current implementation and we can't really
do anything about it until we get a merged front end and get rid of
this __builtin_choose_expr stuff.  right no "vector long" and "vector
int" both map to V4SI (signed) and there's no way to distinguish between
them.

i might end up getting rid of bool altogether out of the FSF version,
unless someone can come up with a better solution.
