The only practical solution will likely be to provide a library that forgoes the native support (from the point-of-view of interface) and provides a portability layer. I have something along these lines in Logtalk:

If I were to redo it from scratch, I'd probaly use a structured term
(instead of a string) as the OS-independent representation, similar to
what you suggested in file_name_parts/2 in http://logtalk.org/plstd/posi.pdf,
and with the added advantage that it covers URIs as well

file_name_parts('http://www.prolog-standard.org:8080/index.html', Parts)
Parts=[protocol(http), host('www.prolog-standard.org'), port(8080),
path('/'), base(index), extension('.html')]
