freeglut (/usr/games/bin/fgfs): Failed to create cursor

The following patch to freeglut-2.4.0 from Vilhelm Sjoberg solve the problem:

Curiously, flightgear installed glut for me not freeglut. All I know is that
his doesn't work with freeglut, but mine does with glut.

I realize this doesn't help a whole lot, but it's all I can say. I do not know
why one user would get glut pulled in and another freeglut. Apparently this is
a common problem with freeglut + flightgear.

Is this patch in upstream CVS already?

I tested that freeglut works with that patch and does not work without.
I have not sent the patch upstream, but someone else may have done it, as 
that piece of code is changed in freeglut CVS (not exactly in the way the patch
suggests),
and from the flightgear site 
http://www.flightgear.org/Downloads/source.shtml

FreeGlut 2.4.0 has a critical bug that crashes FlightGear. If you plan to use
FreeGlut instead of SDL you will need to downgrade to 2.2.0 or run the CVS
version of FreeGlut.

So I don't think we ought too

Sorry, I missed your comment. Could you attach the version of the patch that's
in CVS?

Created an attachment (id=99381) [details]
freeglut-2.4.0-cursor.patch -- taken from freeglut cvs

Both patches work. 

This one, when I kill the fgfs window, still print the Function <glutSetCursor>
called without first calling 'glutInit'.

But except this annoying message, flightgear is ok

Fixed in 2.4.0-r1, thanks!
