> > fast and does not require GCC to be installed anymore!
> > - SIMD code is not generated yet, expect lower performance due to use of
> > scalar code only.
> > - Support for reflections in Elite Force has been removed. We should

> > Some notes regarding compilation:

> > - Get the latest version of the LLVM from their Subversion repository, svn
> > co http://llvm.org/svn/llvm-project/llvm/trunk llvm
> > - Expect a crash under Mac OS X: I know there is a bug in the kd-tree
> > builder, but I haven't been able to locate until now. Maybe someone else is
> > more lucky and could help, which I would appreciate A LOT!
> > - Lightmaps are not sampled yet.
