I just added this to mini-gmp, or more precisely
const int mp_bits_per_limb = GMP_LIMB_BITS;
It's signed, just like in gmp, I have no idea why unsigned is not used.

Why are you using these functions?
If one wants a particular allocation method, e.g., plain malloc, to me
it seems best to use that directly. Or if one wants allocation which is
compatible with gmp allocations, one shouldn't use the *default*, but
the actually registered functions. E.g, in Nettle I have a function
gmp_alloc_limbs (mp_size_t n)
assert (n > 0);
mp_get_memory_functions (&alloc_func, NULL, NULL);
return (mp_limb_t *) alloc_func ( (size_t) n * sizeof(mp_limb_t));
