  Fix env variable tests with new Win32 path rules The new Win32 global path search was not working with the environment variable tests. But when I fixed the test, the new codes use of getenv() was causing more failures (presumably because of caching on Windows ???). This fixes the global file lookup to always go directly to the Win32 API in a predictable way.
