I don't think so. On the other hand, with modern file systems, if I
need a directory that is case-insensitive on a file system that's
case-sensitive, I'll just create a case-sensitive file system at that
point. Doesn't even require root privs these days.

This gets back to user expectations - if foo.c and foo.C are different
files, then foo.c doesn't have a .C extension. If they aren't
different file, then it does. Which means you have to know whether
files are being treated in a case insensitive manner or not before you
can normalize the names.
