Sorry if I mislead. To my knowledge this square sun has been the case
for a long time. The patch I was thinking of comes from the
macflightgear 0.9.10 sources. I have applied it (with a little fuzz)
to pre2 and it does solve the problem. Here it is:

It only happens for me on OS X, I have never seen this problem on
Linux. It happened on my iBook and MacBook running Tiger, and now on
my MacBook running Leopard.
