--- Comment #19 from Richard Henderson <rth at gcc dot gnu.org> --- (In reply to Dominique d'Humieres from comment #18) > Those are files specific to darwin, but I don't think they are the only one > used to build libffi. 99%. Anyway, it doesn't matter. One of you folk that actually have darwin are going to have to debug this. --- Comment #20 from howarth at bromo dot med.uc.edu --- So currently what we have in libffi is a merge from upstream for everyone but darwin which has selective files back ported from the prior release. So this build is untested upstream.
