8.3 names must be uppercase. That's the way MS-DOS worked, that's how
Windows still works (for the 8.3 aliases), and that's the way anything that
reads a FAT volume will assume it works. Lower case letters are only
recorded in the long file names, under VFAT, which I don't believe eCos
supports yet.
