I just tested against the latest 11.2.0 from git, works fine for me. mcf 
threads is not in git, so I suggest contacting whoever you got the 
source code from for help.

While I do have a hunk for the source file in question [1], failure to find `<cstdlib>` is indeed 
something unusual. It is most likely that you didn't install c++ headers into the correct directory, 
so your (stage1 I guess) compiler failed to find them.

Maybe it's useful to change it to stdlib.h?
