Very impressive. That is some sparse 0.5 material.
I will start merging it as soon as I release 0.4.4

I play around with it a little bit, It seems choke on the hello
world program. Shouldn't be hard to fix though.

I attach a patch to limit g++ usage only to llvm related programs.
Currently it use g++ to link other sparse programs.
