Commit 4e90f3185aea9160c28f3eaec5625b67fc0f67db

Build+test bn_mp_set_double.c on more platforms Not all platforms/environments/architectures that support enough of IEEE 754 for the purposes of mp_set_double() actually support enough to legitimately define __STDC_IEC_559__, so only relying on that is too strict. Fixes https://github.com/libtom/libtommath/issues/159
