That may be true, but it's irrelevant. Its external interface via its
command line options follows the Windows conventions. That's all that
matters. It is a Windows executable for all intents and purposes.

Yes, of course. That's hardly surprising.

That's what I do. I have a generic one that converts anything that "looks
like" a file name via cygpath. It's not fool-proof, but the criteria for
converting names could be refined.
The alternative is a target-specific script that understands what all the
arguments options and option arguments are and converts them as needed.
