sorry, but I cant answer this, and cant provide any more info as I did
already; the clang 3.0 which I use on the OpenSuSE 12.1 box seems latest
of what OpenSuSE currently offers ...

# clang -v
SUSE Linux clang version 3.0 (branches/release_30 145598) (based on LLVM
3.0)
Target: x86_64-unknown-linux-gnu
Thread model: posix

# clang -dumpversion
4.2.1

here some defines which might be of interest:
./testver: __GNUC__ = 4
./testver: __GNUC_MINOR__ = 2
./testver: __GNUC_PATCHLEVEL__ = 1
./testver: __clang__ = 1
./testver: __clang_major__ = 3
./testver: __clang_minor__ = 0
./testver: __clang_patchlevel__ = 0
./testver: __llvm__ = 1

Gün.
