Hi,

It compiles ok for me with the latest HEAD and clang 3.70:

    $ make install -j T=x86_64-native-linuxapp-clang CC=/usr/bin/clang
    ...
    Build complete [x86_64-native-linuxapp-clang]
    ...


    $ clang --version
    clang version 3.7.0 (tags/RELEASE_370/final)
    Target: x86_64-redhat-linux-gnu
    Thread model: posix

I do have to avoid using the ccached clang since it gives a (different) error about macro expansions. However, that isn't the issue you are seeing.
