I spent quite some time trying to figure out how it might be possible to 
preserve most of existing behavior while also making the code honor 
--sysconfdir=
There's no way I could find in autoconf to tell whether the use has supplied 
the --sysconfdir= option, so checking for that would probabaly require us to 
add code to parse the command line arguments passed to the configure script and 
see if they contain --sysconfdir=, and that seems like a lot of work for little 
effect.


However, as far as I can see $sysconfdir should always be $prefix/etc when 
neither -sysconfdir= is used.
So perhaps we might use:

if --with-config-file= is supplied ... use it
else if $sysconfdir is not $prefix/etc  ... use $sysconfdir/GNUstep/GNUstep.conf
else if on darwin ... use /Library/GNUstep/GNUstep.conf
else use current rules based on $GNUSTEP_PREFIX
