use of undeclared identifier '__ATOMIC_ACQ_REL' when building llvm-3.1 on Fedora 17

Hi,

I'm getting the following errors, when attempting to build llvm-3.1
(from f18) on my Fedora 17 setup.

  { __atomic_fetch_add(__mem, __val, __ATOMIC_ACQ_REL); }

I've got also a bunch of these:

/usr/bin/../lib/gcc/x86_64-redhat-linux/4.7.0/../../../../include/c++/4.7.0/limits:1404:27:
error: use of undeclared identifier '__int128'; did you mean
'__int128_t'?

and this is with gcc version 4.7.0 20120507 (Red Hat 4.7.0-5) (GCC).

Any ideas on how to fix this? Do I need an updated GCC?

Regards,
