// Hi again...
//
// In reply to my own email, I did some playing around last night
// with the /usr/share/mk/* files, bsd.subdir.mk in particular, and came
// up with:
//
// _SUBDIRUSE: .USE
// @for entry in ${SUBDIR}; do \
// (if test -d ${.CURDIR}/$${entry}.${MACHINE}; then \
// ${ECHODIR} "===> ${DIRPRFX}$${entry}.${MACHINE}"; \
// edir=$${entry}.${MACHINE}; \
// cd ${.CURDIR}/$${edir}; \
// else \
// ${ECHODIR} "===> ${DIRPRFX}$$entry"; \
// edir=$${entry}; \
// cd ${.CURDIR}/$${edir}; \
// fi; \
// ${MAKE} ${MAKEFLAGS} ${.TARGET:realinstall=install} DIRPRFX=${DIRPRFX}$$edir/); \
// done
//
//
// The only change is adding ${MAKEFLAGS} to the ${MAKE} line so
// that the -j3 flag carried down into the subdir's, so that make world
// works with parellel make...
//
// Is there any reason that I'm overlooking why this *shouldn't*
// be done this way? If not, and there are no arguments against it, I'd
// like to make the change a permanent feature...?
//
Yes. If this worked you would create 3 copies of make for EACH subdirectory...
