Bug #1

The build system is in serious need of a clean-up, but the main focus should be to switch to a newer version of Autoconf and/or provide something as portable to older systems as the current solution is.

After doing this, aclocal.m4, config.guess, config.sub, etc can be moved out of the source tree, but a replacement will be needed for the extensive config.h facilities provided.

Using automake should simplify things a lot as well.
