Perhaps this could be implemented in two steps.

(a) Implement:

    #if msys

      $ foo

    #else

      $ bar

    #endif

using good old hghave, then

(b) roll hghave into run-tests.py

I think doing (b) doesn't affect the syntax. So we could start using (a)
before we have an implementation for (b).
