I added these. Thanks

APPKIT_DECLARE should only be used in source files, not headers (in fact 
APPKIT_DECLARE just might be useless now). I've fixed the gui headers 
for this.

Perhaps the LFLAGS need a -R/usr/X11R6/lib rather than (or in addition 
to) a -L/usr/X11R6/lib (I think this is done for libraries). Perhaps you 
could try that in gnustep-back's config.make and see if it works.

It's up to you. I wouldn't know how to fix it.
