  I suppose that if one doesn't use the macros that depend on
  GMP internals, there should be no problems. In particular,
  udiv_qrnnd is not used, unless the user configured MPFR to use
  the GMP internals, but then that's the user's own problems.

There is a symbol LONGLONG_STANDALONE which mpfr might want to use.
It is documented in longlong.h's header.

Unfortunately, it is has been used everywhere it is needed, but that's
easily fixed.  I checked in a missing test of it now.
