This is how we're able to see the missing output file (and double space) after the -o option. We've been using this cc.rex for 2.5 years; I'm pretty confident it isn't the problem.

Can you post the generated build files for the try-compile that hangs?

Run cmake with --debug-trycompile to get it to save the files.

Although since it hangs, I guess CMake never gets around to removing the 
files.

Anyway if you could tar up the build tree, I can take a look.
