Problem with $DISPLAY

[Michael Crawford]

One can choose whether one's new filesystem is case-sensitive when one
initializes it with Disk Utility.

I don't recall when they added case-sensitivity but it was sometime
around tiger or leopard.

While the C programming language is defined to be case-sensitive, I
don't think UNIX enforces that definition.  It depends on the
filesystem - consider mounting an 8.3 FAT floppy.
