Yeah, this is a known problem caused by autoconf doing its "is this
function declared" test in a way that clang doesn't play nice with.
There's a fix for this upstream:
http://git.savannah.gnu.org/cgit/autoconf.git/commit/?id=82ef7805faffa151e724aa76c245ec590d174580
and we've been patiently waiting for an autoconf release that
incorporates it ...
Thanks - I’ll add my voice to the release requests.
