It's a "known" problem with the Joliet spec - the spec allows for case
senstive file names, but Windows doesn't. I guess the Linux Joliet driver
code "mimics" the way Windows would see the CD.
The work round on a Linux/Unix system is to use the Rock Ridge extensions.
It has been suggested in the past that checks could be added to the code -
for example, the strncmp() in joliet.c could be replaced with strncasecmp()
for files and where directories share the same case insensitive name, their
contents could be merged. Probably needs a "-joliet-strict" option ...
