Sometimes it may be best to leave solving a problem until other changes
have been made that facilitate it.  I think this is such a case.  The
relevant other changes are either making cpp0 be a special mode of cc1
(and preferably merging tradcpp into cc1 as well), or a specs redesign
that makes it easy for the driver and back end to come to the same
conclusion about the type of size_t.
