I was wondering why we have autoconf213, automake14, and automake15 still in 
the repo? I was able to eliminate them from my build tree 2 years ago. Also, 
is there any reason to keep byacc? I was able to substitute bison for 
everything that wanted byacc and eliminated it from my buildtree too.

Just curious...
