Thanks! Stopping with this error is what I expected for "official" 
windows versions. This means if we want to write SDL supporting both 
normal POV-Ray releases and forks for windows users, we'd need to strip 
"unofficial" from #version.

Thanks jr, for the initial versions.inc template. Yes, such an include 
could be provided with code. However, we'd need to be careful about 
'declaring' any version of POV-Ray to be an official one. Today ONLY the 
pre-compiled windows releases are official.

Hmm, suppose we could extend this code to optionally end with an #error 
if the desired hook or fork is not found for SDL written specifically 
for a particular fork.

I don't know, I think it was likely some unfinished effort where some 
initial code got copied. Code wise it was always a match for f_cushion() 
and so pointless as shipped.
