Sounds like a great idea.  Regression testing is always welcome.

As long as the dependency is for development purposes only, I don't see
a problem.  Though, committing a generated database to CVS wouldn't be
an awful idea either. ;-)

Right.  Make test could also be run after a test install directory were
created.  As was mentioned in a reply to this post, it's possible to set
up the prefix to a usable test installation directory.  My configure
call is usually something like this:

	$ mkdir +build +install ; cd +build
	$ ../configure --prefix=`pwd`/../+install \
	> --with-gnats-user=$logname
	$ make install
	$ cd ../+install/usr/libexec/...

I do agree that enhancing command-line options would help immensely.

We could always start another CVS repository for the test data and test
suite if that would be "easier".  I would be fine with simply creating a
"test" directory.  Is your testing suite a unit-test style?

I had been looking at GNU Nana [1]_ for design-by-contract patterns that
might be helpful.  The CPP macros work best with gcc and gdb, so it's
not 100% portable to other compilers/debuggers.  Might be worth looking
at, in any case.
