Cog should continue to work if LLVM is correct.  At Qwaq/Teleplace we used
the Intel C compiler on Mac and it worked well.  So Cog *should* work with
any C compiler.  I have at least built Cog with LLVM.  The -O2 production
VM crashes (in trying to create the Closed PIC prototype on initializing
the JIT). But the -O1 assert and -O0 debug VMs do work.  So I think
long-term we will be able to move to LLVM.  It's clearly not ready for
prime time yet.
