I have two machines, a linux box running ubuntu and a mac laptop.
These errors were produced on my laptop with a fresh checkout (so
there's no chance of compilation mix-ups unless they're in the tree).
I only have the gnu compilers (cheaper than intel licenses :) ).

I'm guessing it's probably something to do with double-underscores
maybe? I do see double-underscores in my error message that I posted
here.

Thanks!
