The best thing to do is to avoid using environment variables,
*especially* for embedded interpreters.

On Windows, I would always modify the "Version" (which is now in a
resource) to effectively create a private distribution. In the registry,
I'd set up PythonCore/MyVersion/... keys. At that point, it just always
used the keys that I set.

Since you're building an embedded version, then you may as well set up
that version to have the proper paths within it, rather than relying on
external factors which can change...
