> Does anybody know why Make started behaving like this?
Yeah, it comes from the target which "makes make" during the bootstrap
phase in /usr/src/Makefile. Here's the relevant fragment:
cd ${.CURDIR}/usr.bin/make && \
${IBMAKE} -I${.CURDIR}/share/mk -B ${CLEANDIR} ${OBJDIR} depend && ..
This unfortunately has problems because (assuming that ${CLEANDIR} =
"cleandir" and ${OBJDIR} = "obj" of course) when make first starts up
it goes looking for an appropriate shadow obj tree so that it can
point the ${.OBJDIR} variable at it. Because there's no obj dir yet,
it sets ${.OBJDIR} = ${.CURDIR} as a fall-back. Now the cleandir and
obj targets are run and the obj dir *does* get created but it's too
late for that invocation of make, which has already made up its mind
about that. When the depend runs, it's with the bad ${.OBJDIR} value.
Satoshi fixed this by breaking the depend off into its own make
invocation, but apparently this had other undesirable side-effects and
I think he's still looking at it.
