Clang is largely compatible with most gcc command line options, although
I suspect a lot of the funky -f flags are not supported; clang is also
now able to compile mozilla-central, and even boost and qt, so it's
probably pretty usable.
One of the design goals for clang is to be a drop-in replacement for
gcc. clang is not finished yet (it's a software project after all!) but
for almost any project, simply switching CC and CXX to point to clang
and clang++ binaries is enough. If you do find issues with it, please
report them to the LLVM project (which is pretty responsive on bug reports).
Cheers,
