Emacs and vi both handle the cross case pretty well. The "editor
integration" all takes place via parsing the compiler's stdout -- it
isn't difficult to make work for almost any case.

If you're a developer, you know how to type "make" already pretty
well. error(1) is stock C. If someone is desperate for a copy that
will compile for normal Linuxes, though, I can make one available.
