To clarify my question:

C-- looks like a cool idea, but not very actively developed. I would
expect to run into bugs or just missing features.  Some parts are
obviously more suited for compilers than say C, but I would expect GCC
(and to some extent LLVM) to be more mature and have better
optimizations. I would need to see some evidence of C-- being used by
someone else than original author before trying to evaluate it.
