Haven't you been reading your commit mail? :-)  I discussed the bug in
cvs-committers yesterday.  Perhaps I removed the cc's to the general cvs
lists.

The diagnosis of a bug in the log message for rev.1.146 was obviously
wrong, and the "fix" turned out to introduce the current bug without
actually fixing the old one.  Now, if the obj directory already exists,
then `make' shoots itself in the foot by removing its current directory.
Then re-making the obj directory does not help.

Untested fix (for -current):

diff -c2 Makefile~ Makefile
*** Makefile~	Sat Sep 27 01:42:58 1997
--- Makefile	Sat Sep 27 01:53:47 1997

  	cd ${.CURDIR}/usr.bin/make && \

! 			${CLEANDIR} ${OBJDIR} depend && \
! 		${IBMAKE} -I${.CURDIR}/share/mk ${MK_FLAGS} \
! 			all install clean cleandepend
  	@echo
  	@echo "--------------------------------------------------------------"
--- 223,233 ----
  	@echo "--------------------------------------------------------------"
  	mkdir -p ${WORLDTMP}/usr/bin
+ .if !defined(NOCLEAN) || !defined(NOOBJDIR)
  	cd ${.CURDIR}/usr.bin/make && \
! 		${IBMAKE} -I${.CURDIR}/share/mk ${CLEANDIR} ${OBJDIR}
! .endif
! 	cd ${.CURDIR}/usr.bin/make && \
! 		${IBMAKE} -I${.CURDIR}/share/mk depend && \
! 		${IBMAKE} -I${.CURDIR}/share/mk ${MK_FLAGS} all install
  	@echo
  	@echo "--------------------------------------------------------------"

This also removes the superflous final clean and cleandepend steps.
