I can reproduce that with the same clang version and current HEAD.

I have just posted a patch to fix that.

For the gcc problems I cannot tell, except that it might not be able to compile
the Apple API-headers. This is an issue for some compilers but nothing we can
fix afaik.

Thanks for reporting!
