* r5689 undone: some casts were incorrect (mp_exp_t may be greater thanvlefevre2008-11-221-2/+2
| | | | | | | | | 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). git-svn-id: svn://scm.gforge.inria.fr/svn/mpfr/trunk@5690 280ebfd0-de03-0410-8827-d642c229c3f4
