These errors are absolutely gnu89 related.

If you test with libc++ you'll hit an issue with GAMESS. I have an
outstanding patch and src.alt which I need to get off my butt and get
approved. (I'll try to get that formalized this week or next)

I don't know about that particular version of binutils, but I'd
strongly recommend manually installing 2.25.

As of this week I'm officially participating in SPEC CPU work. Part of
that role is testing the upcoming benchmark "v6" on systems and
compilers which others may not have tested yet. I hadn't planned to
test vanilla clang, but if there's interest let me know. (On or off
list is fine)

(Sorry - I don't mean to hijack this thread. Just want to help with
SPEC related things if I can)
