It occurs to me that that FAQ entry could be better worded to make it clear that FAT != FAT32. The entry in the UG section on the
$CYGWIN environment variable is already clear, but how about something like the attached, or perhaps it would be even clearer if it
listed which OS versions use which fat versions?
