Could you instead invoke "make install" on just one host, and "make install-arch-dep" on the remaining platforms? That should install just one copy of the architecture-independent files. If this doesn't work now, perhaps we should make it work, or add another makefile rule that would work. > With today's disk sizes, > that is a minor difference that I'd be happy to give up, saving time > in the future for every emacs library loaded dynamically into an > editor session. It may make sense to have a build-time option to not compress, bit I thought the point of compressing was to improve performance more than to save disk space, since these days CPU cycles are often cheap compared to I/O. Have you measured the performance of Emacs startup with and without compression, if the startup files are cached and/or not cached?
