I don't recall there ever being such a problem with Interix.

Interix runs in NT's POSIX subsystem, so there isn't even a
compatibility library to link against.  It's been a long time since I
worked on Interix support, but I don't recall anything in there that
would cause problems, any more so than any other proprietary OS
running gcc.

OTOH, I haven't looked at its license either.
