I don't think it should make any difference.  Function 71A8h doesn't
hit the disk, it simply runs the algorithm used by Windows to generate
a short alias for a long name.  That's why this function works even
for non-existing files, and that's why it returns a name without a
numeric tail even if numeric tails are in effect.  It doesn't read the
directory, it just transforms the name in memory.

I think your assumption is wrong: this isn't related to FAT.  Try
running `ls' on c:\winnt (or whatever it is called on XP) and its
subdirectories, and I think you will see lots of UPPER case.

In addition, many Windows systems have files copied from DOS disks
which Windows in its infinite wisdom copies without downcasing the
string stored in the long name part of the directory entry.
