1) It would be more efficient if you turned most of these into
   CPP-level builtin macros -- the values to define them with would
   have to be poked into the library at initialization time, but
   that could be a structure and a single function call.

2) Why do you have both __TARGET_FLOAT_FORMAT__ and
   __TARGET_USES_VAX_*_FLOAT__?

3) Do we _really_ have targets where bit endianness != byte
   endianness?  I realize they are distinguished at the tm.h level,
   but I suspect in practice this does not happen.  Same question
   about (integer) byte endianness and word endianness; there I know
   code exists that blindly assumes the two are the same.
