I thought so and that is a problem.  I was of course talking about the
user view.

Depends on what you mean by case-sensitive.  I tested this yesterday
before posting.  My test was:

  $ echo 1 > test
  $ echo 2 >> Test
  $ cat test
  1
  2
  $

That was the result on my Linux/PPC (2.4.0) system both for a mounted
FAT floppy image and an NT volume.  Those systems do not even support
case-sensitive operation in a strict sense of the word (NT servers
could in theory support it, but it practice they don't).

We could conclude that the problem is not easily solved on GNU/Linux,
or that it can only be solved with a user setting, but the situation
on MacOSX is still pretty clear.
