The only real way to handle it properly if you have no advance knowledge of the filesystem is to query the OS for the proper casing. Mac OS X has this ability, it's probably available in other case-insensitive case-preserving environments too if we wanted to bother with it.
A far simpler thing to do is just write out a mixed-case filename and
see what you get back from readdir() to test for case preservation. For
case sensitivity, just write out a filename and try to open it with a
different casing.
Oh, you're describing how to determine how the current system deals with cases. I was describing how to determine the casing of a file when you already know you're on a case-insensitive, case-preserving FS.
