curt 9fe889e404 Frederic Bouvier:
I made these changes because fltk doesn't recognize path
\\SERVER\SHARE as a normal directory, although plib/ul
function succeed at enumerating the content of such a
path.

I had that problem when I decided to test FG on a loaned
HP xw4100 workstation. I installed it over the network and
the install-source became \\myserver\myshare\. with no
scenery files detected.
