The problem here is that pr_debug expands to gmp_printf which is not 
part of mini-gmp and the little replacement mpz_printf I added only 
allows for formatting a single mpz_t (which is enough for all the 
non-debug cases).

So there are 3 options basically.
1. Try to make gmp_printf standalone and port it from libgmp to mini-gmp.
     This looked like a huge and complicated effort and would likely 
blow up stuff considerably again.
2. Replace pr_debug's gmp_printf with regular printf and rewrite all the 
debug-calls to mpz_get_str()
     and free() which sounds painful.
3. Simply disabling debugging with mini-gmp.
     Easy way out without obstructing things too much otherwise.
