Okay, to be more specific: The default target (typically "all") will now 
always detect that changes occurred (which is true, but they are not really 
desired changes) and thus always rebuild everything if you invoke make without 
a particular target.

In other words, to prevent make from rebuilding everything, you now always 
have to give an explicit target file to be built.

That situation is even worse if you want to modify one song and rebuild the 
book as well as the song... You can either manually give make the list of 
files that needs recompiling (i.e. you need to know the file names of the 
output files of all the really changes songs, plus the book; which totally 
defeats the dependence checking of make) or make will recompile all songs, 
even those that have not been changed by you...

Either way, for huge projects (and this issue of unwanted midi files is only 
an issue for huge projects) neither option is really compelling...

Cheers,
Reinhold
