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.
John
