You're most welcome.  I'd like to share more.  If I knew
off-hand how to do more with configure, I'd probably have gone
further.  Perhaps I'll find the time to learn and followthrough. :)

I'm attaching a patch with this documentation.  Am I being too
verbose?  This patch is against the latest CVS revision of the docs.

I actually stumbled upon it by near accident.  It's a LGPL'ed
near-equivalent to Purify (at least with respect to heap
allocations).  I personally like it better so far.  Here's a link.

Click on the not-entirely-obvious "Online Documentation" image near
the bottom of the page to see the very extensive manual.

That sounds very useful.  I plan to generate the debug version by
hand for now.  Maybe doing that a few times will reveal how it can be
automated :)

Thanks!  Glad to be able to contribute even a little.
