[zooba]

The _findvs module I added for distutils has added load-time dependencies on the ole32 and oleaut32 DLLs.

To reduce startup time, we should move _findvs into its own .pyd (unless I hear a better suggestion, I like "distutils._findvs.pyd").

[zooba]

Actually, I'd prefer not dropping it into the Lib directory, so probably DLLs/_distutils_findvs.pyd is the way to go.
