No, ideal for changing the default a whole subtree is to put the change in Makefile.inc at the top of the tree and inherit this recursively. The MAKEFLAGS hack fails for normal builds (when `make' is run in a leaf directory) because it doesn't affect the current invocation of make. Only the setting of LIBDIR in bsd.own.mk is wrong if a Makefile[.inc] changes OBJFORMAT. This is fairly harmless except for installng libraries. Bruce
