Do you want to make make all install faster when a make world has been done already and all the objects sit still there in the tree? I think this is not what we want. Make world (which includes cleandir or is it clean?) is slow because the libs are being built several times during the course of makeing the world. > > Michael-- > Michael Elbel, Digital-PCS GmbH, Muenchen, Germany - me@FreeBSD.org > Fermentation fault (coors dumped) > --Chris Christoph P.
