OK, I've changed it to output a version number determined compile-time  
from the toolkit, currently one of:

gnustep-gui-###
apple-appkit-###

Yavor, if you decide it's better to report the GNUstep base version  
also, you can use NSFoundationVersionNumber for OS X.

There are four other files where I replaced 9.0 with 23.0.60 or  
variants of it.  Eventually it would be nice to do this automatically  
with autoconf.  In this case it is important NOT to include the  
extra .# build number that emacs' build system generates.  This, by  
itself, *should* be used for the CFBundleVersion in the Cocoa  
Info.plist however.
