r5689 undone: some casts were incorrect (mp_exp_t may be greater than
mp_prec_t, so that casting a mp_exp_t into a mp_prec_t can introduce a
bug). There may be bugs in some cases, but the casts fix the symptom,
not the bug (unless one casts the unsigned type to a signed type that
is *strictly* larger, which is not possible here).
