Using that technique, instead of executing copies of make in subdirs, you include pieces of makefiles from subdirs and end up with only one dependency tree. This gives you cleaner, more accurate builds with less spam. It's harder to convert a build system to that format than it is to use it when making one from scratch :) -- Rafael -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
