A similar problem would be filename completion. We have separate code
paths for that in Windows/Unix I believe, even though on MacOSX, the
file system tends to be case insensitive, too (and normalizing utf-8
composed characters in some manner).
If we could design some sort of system call sequence that worked out
insensitivity/normalizing agnostic, this would mean that on a typical
GNU/Linux system which can mount various foreign file system types,
everything would work out according to expectations.
That would seem to be preferable to #ifdef and its ilk. I think,
however, that stuff like the "\\" directory separator can be system
rather than file system dependent.
