If I interpret it correctly, the user reporting bug 17938 is trying to
use a native NTFS filesystem with Wine, which we already know is a bad
idea :)

But his bug raises an interesting issue. If an application has sanity
checks on FAT32 vs NTFS (e.g., I need a 4GB file ... I've detected no
NTFS therefore it's FAT32 which doesn't support more than 2GB files),
then we might just have to make this configurable, possible on a
per-app basis.

My suggestion is a drop-down box in the "Advanced" tab of "Drives" to
control filesystem type (separate from disk type, as is suggested in
Comment #7 on 17938). It shouldn't be important for floppies or even
CD-ROMs, but the options could be:
- Default (autodetect, fall-back to unixfs)
- FAT12 (floppies)
- FAT16
- FAT32
- NTFS (probably don't need different versions on NTFS)
Possibly restrict these to CDROM type:
- ISO9660
- UDF

Unless someone can come up with a better default than unixfs :)
