No, I don't think that's safe. Linux users may have set it up as a mountpoint for
their DOS C: partition, or as a symlink to the relevant mount point or device.
Not THAT likely, but IMO more likely than the test for DJDIR and DJGPP causing
false positives.

True; this was my original reason for not using it (as I stated when DJ suggested it).
