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.

Yes, but the default is sane too: /etc

So we could use it blindly.

(I'm only confused at why the autoconf-provided string says [PREFIX/etc] to be the default.)

 

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

I was under the impression $GNUSTEP_PREFIX was supposed to be the same as $prefix, but if not, this looks right (apart from $sysconfdir not seeming to include $prefix when I was trying it out -- I will confirm this).

If $GNUSTEP_PREFIX is the same as $prefix, we can simply skip branch #2 ("else if $sysconfdir...").

I'll see what I can do.
