Hm. I don't think I saw that message?
Certainly there are obscure cases where enabling DOS path support will
behave differently, but they're pretty rare I believe. Is this a Cygwin
thing?

This would be very tricky: right now all the code to do DOS vs. POSIX
pathnames is controlled through #ifdefs, so it's a compile-time thing.
Changing it to a runtime thing would be a lot of work, I think... the
#ifdeffing in GNU make is kind of a mess, with all the different ports
we support.
Honestly, I don't see a lot of benefit to it. On a Windows system, even
in Cygwin, I would assume that everyone would always expect anything
that looked like a Windows pathname to be treated like a Windows
pathname. We're not talking about enabling this support on UNIX, just
in Cygwin.
