Please look here:

I'd suggest late versions of GCC 4.0.x.  The 4.1 series has had numerous 
problems compiling LLVM on x86-64, though some people have had success 
with some vendor versions.

Please file an llvm bug report with these errors.  It may be that we are 
doing something illegal in C++  that is only now getting caught.  If the 
source is valid and G++ is incorrectly complaining, please file a bug 
against GCC.

Yes, it can be, and it works.
