If we can use a style that's clean to various warning levels etc, then
we should do so, as long as it doesn't make too much of a mess.

It might be that your problem is arising from C macros like
mpq_numref.  Maybe we can use a C++ friendly definition of those in
gmp.h (for C++), or alternately use _mp_num etc directly in gmpxx.h.
