I use NAG with llvm-gcc4. What sort of errors do you get? Did you
configure llvm-test with the appropriate flags to find it?

Someone needs to do the work to test gfortran and fix any problems it runs
into. I'm not aware of anyone doing this, though it's probably not hard.

On some testers, yes. This one is:

What problems are you hitting?
