This is a bit tricky, as GNUSTEP_OBJ_DIR gets set in common.make, but 
since it really isn't needed until actualy compiling (and a clean which 
I though doesn't invoke instances might just clean the GNSTEP_OBJ_PREFIX 
directory, I figured that I'll just move the definition to 
Instance/rules.make. So for testing I introduced GNUSTEP_OBJ_DIR_ROOT 
which is set in common.make to the same value as GNUSTEP_OBJ_DIR  was 
originally set. Then in Instance/rules.make I set GNUSTEP_OBJ_DIR = 
$(GNUSTEP_OBJ_DIR_ROOT)/$(GNUSTEP_INSTANCE). (after the targets and 
before the other variables are set.)

Well make from here resulted in errors do to the target definitions in 
rules.make (notice NO Instance/) which refer to $(GNUSTEP_OBJ_DIR)/5$(OEXT).

Then "just for fun" I also set GNUSTEP_OBJ_DIR = $(GNUSTEP_OBJ_DIR_ROOT) 
in common.make right after GNUSTEP_OBJ_DIR_ROOT was set. Still my 
Instance/rules.make would override GNUSTEP_OBJ_DIR to append the 
$(GNUSTEP_INSTANCE). I figured that this will probably cause problems as 
the var would have different values in different stages of the make 
process. But alas, this was not so! I actually reuslted in what I 
wanted!  Even make clean cleans the 
$(GNUSTEP_OBJ_DIR_ROOT)/$(GNUSTEP_INSTANCE). This behavior is better 
than I expected, as I could clean the projects sepratly now (still using 
ifeq ($(wonames),wo) to set the FRAMEWORK_NAME, but once I get 3 sorted 
out, I take it everything will be cleaned)!

I'm not quit sure, but I think it would be more correct if these targets 
in rules.make where moved to Instance/rules.make but as it's currently 
working fine for me, I'll wait for your comments on the whole issue. 
(Maybe I'm really breaking something here.  Once I'm finished I'll try 
recompling everything with the modified make version.)

Cheers,
Dave
