We should use MPFR to evaluate c99 lgamma function (and the common extension
function gamma). However we have to wait until MPFR implements a suitable

(They're actually easier because I get the signgam identifer as a pointer parameter rather than having to find it at global scope.) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=30250 ^ permalink raw reply [flat|nested] 5+ messages in thread
