enable error reporting.

This is part of an effort to standardise our autotools setup across
project to simplify maintenance.

 portability. Here are some things you should have on your system in order to
 compile the git repository tree :
 
-  - GNU autotools (automake >=1.10, autoconf >=2.50, autoheader >=2.50)

     (make sure your system wide `automake` points to a recent version!)
