You need to change a few more things to get bare basic support:
if (UNLIKELY (new_alloc > ULLONG_MAX / GMP_NUMB_BITS))
if (UNLIKELY (new_alloc > ULLONG_MAX))
Also you cannot use /mpz/inp_raw.c mpz_inp_raw and /mpz/out_raw.c mpz_out_raw unless you modify them. I don't use those functions so I don't bother modifying them.

Subject: _mp_alloc to long int
A project I am working on, requires more than 2^37 limbs, more than a 64 bit system would allow, if mp_alloc is set to int. When I manually change it to long int, recompile and run, I get a segmentation fault, particularly in mpz_set_ui through gmpxx. Would you be willing to shine a light on what needs to change within the program to make it possible to make this change?
