Frankly I don't see how that's relevant. Nothing we've discussed is
as stupid as that ;-)

Actually IIUC that's equivalent to the following Jamfile:

project_root ;
COMMON = main.c version.c work.c util.c ;

exe foo : $(COMMON) foo.c ;
exe bar : $(COMMON) bar.c ;

...which is exactly the same number of lines. Autotools have the
advantage of being available on most UNIX systems, but lack many of
the advantages of Boost.Build.
