Comment(by jpflori):
The files randbui.c where gmp_urandomb_ui is defined are similar in GMP
(5.04) and MPIR (2.1.3.p9 in Sage).
They only call _gmp_rand defined in gmp-impl.h which looks quite similar
as well (in fact I saw no diff but did not check completely, there could
be some black magic somewhere deep enough).
From what I see in integer_ring.pyx and more specifically in the
_randomize_mpz function where c_random is called as well, there is no
different sections for 32 and 64 bits, nor different doctest in
randstate.pyx (only rgp from Pari does change), so I guess it is not that
unsafe to assume that MPIR behaves the same for both.
