Apple clang version 3.0 (tags/Apple/clang-211.9) (based on LLVM 3.0svn)
Target: x86_64-apple-darwin10.8.0
It's part of the Xcode 4.2b7 package.
Shall I try to compile it on my own?
Thanks, Akos

And I still get the following warning:

John,
The version from the Xcode 4.2 GM package (Apple clang version 3.0
(tags/Apple/clang-211.10.1)) still has the same problem. Which version should I
use?
Thanks, Akos
