The seem to be essentially OK.

The objwarn changes seem to be a bit too decentalized.  Did you try
putting them on the `all' target?

Please recover the description of MAKEOBJDIR from an old version.
Oops, its semantics has changed.  The .${MACHINE} suffix previously
didn't apply to it (the same path was bogusly search twice).  Please
fix this.

^^^^^^^^^^^^^^^^^^^^^^^^^ /usr/obj`cwd` (/usr/obj = default MAXKOBJDIRPREFIX)
>${.CURDIR}

Also, if MAKEOBJDIRPREFIX is not set, but MAKEOBJDIR is set, then the
path is:

${MAKEOBJDIR}.`uname -m`	# shouldn't search here
${MAKEOBJDIR}
/usr/obj`cwd`			# shouldn't search here
${.CURDIR}

>If it IS set, then the order is
>${MAKEOBJDIRPREFIX}`cwd`
>${.CURDIR}

Also, MAKEOBJDIRPREFIX has priority over MAKEOBJDIR if both are set.
