Tho sometimes this can be fixed by building those tools twice: - once for the target - once for the host (to run it during the build). E.g. I think we could build almost all of Emacs's files via cross-compilation, the only exception being the dumped Emacs (i.e. the .pdmp files): we could build a "host-temacs" which we can use to compile the .elc files and then a "target-temacs" for the actual intended target. But generating the target .pdmp file requires running the target-temacs. Stefan
