   TODO -- reconcile the two quad types (QUAD_TYPE and quad).  These
   functions really are defined as using the structure quad, but it's
   irrelevant, as long as you don't look at the bits...  quad is
   defined to be a structure of two doubles, while QUAD_TYPE is a
   structure of four ints...  so, this is a hack, just to get this
   to compile (I really should have included quad.h from common/tdt/MIPS,
   and done something to reconcile the two kinds of quad types).
