Does the current seeding conform to some informal standard? Do we want
to generate same sequences as other mersenne twister implementations, or
is it only an issue of whether or not we want to change seeding and
generate different sequences than earlier GMP versions?

I think we can use even smaller limbs for testing purposes, with
mp_limb_t defined as some magic C++ type.
