With Windows, you're free to use either path separator.  With Cygwin,
you're life will be easier if you use '/' though it will accept '\' too if
properly escaped.

Cygwin understands UNC path syntax using '/'.  I would expect
Windows to be cranky about '//' as a UNC path indicator though.
If you need the source to compile, link, and run appropriately
on either compiler, then you need to port it so it will, if that's
what you're concerned about.
