But then, does it matter? When you download something and start to compile
it you don't expect it to finish compiling in 3 seconds, do you? What is
the point if the compilation takes 10 minutes or 13 minutes? You only do
it once. An if you compile an own project I suppose you don't do 'clean'
rebuilds all the time, only when some central API changes or something
similar, maybe once a day.

I rather have many Makefiles, as long as it is clear what happens...
