Another idea would be to do something like make install DESTDIR=built-on-`date +%Y-%m-%d_%H-%M`, so that even if you do not wish to install globally whenever you build Emacs, you at least have past successful builds in a convenient place. Ultimately, however, I think "make bootstrap" should avoid doing lots of implicit things like deleting old builds. It should be reversible somehow without needing to know bzr hacks or redirect the output of previous builds. Automated functions that make a mess should clean up after themselves. -- Regards, WGG
