Not too hard, given that ECL controls how gmp is built. Maybe you will have
to change the gmp makefiles to add further flags and make GMP_... macros
depend on some define. I would advise to define __GMP_BITS_PER_MP_LIMB
and the other macros as a function of something like FIXNUM_BITS -- this
will be necessary because gmp.h is included by ECL also when compiling
other people's code.
