Please note that the above code is from Thomas Dickey. I believe it will 
be in his next release (so we can remove the patch then). A quick look at 
the dialog code, I see that the fopen(3) calls use a mix of comparing with 
NULL and with 0. I don't know why the code uses both ways. Please feel 
free to discuss this with him.

(At this time, dialog in pkgsrc is not the latest release, but the fix is 
not in dialog-1.0-20051030 either. I had updated to dialog-1.0-20051030 
originally to test on DragonFly before discussing with the developer.)
