Just a small note on 'make.erl': 'make:check_includes/3' slows down compilation a lot if
no header file actually changed. The function has to peek into modules to check if they
include a header file which is newer than the object file. We circumvented that by
building a simple dependency graph on the first compilation run on a clean project. In
essence, this comes down to what erlang.mk is apparently doing as well in erlc.mk.
