_get_volume_info returns the filesystem type, except that it calls a 
function from the LFN API, and so doesn't work on NT :-(

Does NT even support FAT32 for its DOS box?  Does anybody have access to 
such a system to check whether FAT32-specific DOS calls work on NT, 
both on NTFS and FAT32 partitions?

If FAT32 is not supported by NT, then we could simply detect NT (by 
looking at the DOS version number) and return -1.  Or perhaps leave it at 
FAT16, since if the filesystem is FAT, that's the truth.
