Re: Upper/lower case filenames.

The problem here is Linux, not Windows, and not Cygwin.  If you create an
8.3-compatible filename under Linux, it does not generate a long filename
entry for that file, even though it should.  As a result, the only name
Windows knows is the short name, which is all uppercase.

The solution would be to have Linux's vfat driver generate long filename
entries for files whose names are not uppercase.  Or, even better, generate
long filename entries for all files created or renamed by Linux.

When you create an 8.3-compatible filename that has lowercase letters in
Windows, it actually writes a long filename entry to preserve the case.
Linux should do the same, but doesn't.
