Subject: Convert the source code to use ANSI C style function definitions and
 enable the automake ansi2knr capability.

Right now this doesn't quite build using a K&R compiler because of a
problem with the loadavg test program, but the rest of the code works.  I'm
asking the automake list about this problem.
