This test just grabs xxmodule.c from Python to try out a compilation.

It's a lot of work just to try out a .c file in build_ext. I've already changed this in trunk by having a c file local to distutils tests, as a fallback in case the location cannot be found (depending on the execution context).

I can backport this to 2.6. It's pretty safe to do it since its just a change in the test, the distutils code is not changed. Barry let me know if you want me to do backport it in release26, and if yes, when I should do it.
