// If /usr/obj-stable is ever used, it is incorrect. /usr/obj is the
// *only* directory ever used for the object tree. It should be building

// directory /usr/obj/usr/src-stable/.


Ok.  So how do you explain this ?

My src-stable/Makefile, at lines 143-148 is like this:

...
        here=`pwd`; dest=/usr/obj`echo $$here | sed 's,^/usr/src,,'`; \
        if test -d /usr/obj -a ! -d $$dest; then \
                mkdir -p $$dest; \
        else \
                true; \
        fi; \
...

Hence, if my current directory is /usr/src-stable, $dest will get the
value "/usr/obj-stable".

// 
// If you can be more specific about the 'some parts' and locate
// problems with specific makefiles, then use send-pr. NONE of the
// source tree should be looking at /usr/obj-*anything*, and the
// macros that enable this are all common (in /usr/share/mk).

I don't fully compreend all that makefiles (yet).  All that I know
for now is that when I do a make obj, the links are created pointing
to obj-stable, but the real directories are created in /usr/obj.
