Seems clean and straightforward.

Is something like the following too tricky?

   #ifndef MINI_GMP_LIMB_TYPE
   #define MINI_GMP_LIMB_TYPE long
   #endif

   typedef unsigned MINI_GMP_LIMB_TYPE mp_limb_t

As only unsigned types are supported...

Then, should we adapt the Makefile target check-mini-gmp in such a way 
that it can handle
   make MINI_GMP_LIMB_TYPE=char check-mini-gmp
?
