That's not really a problem with hfs. While hfs ignores case for lookup,
it preserves case for creation. So if you create foo.C, it will always be
foo.C. It will be found if you look for [fF][oO][oO].[cC], but it will
always be foo.C.

This only would be a problem if you had both a foo.c and foo.C (or foo.s
and foo.S).

From asking around, I confirmed that recent FAT file systems (ones that
are more than 8.3) also are case insensitive but preserve case. So
programs are in the same boat there too.

Take care,
