Once upon a time, I had a working web page: http://autogen.sourceforge.net/conftest.html
(It is down because the underlying OS was upgraded and it was a nuisance to find a build platform that produced binaries that worked correctly on the current platform. I've since learned how to do it, but it is not a round tuit I've gotten around to.) Anyway, a number of people used it when it was alive and were happy with the results. The underlying templates need updating due to autoconf changes, but the concept is straight forward: lead a user through a few forms to find out what condition needs to be tested and what ought to be done if it turns out to be true or false. I found discovering that on my own to be way hard. Cheers - Bruce P.S. If anyone asks me, I go find my round tuit and get that page working again.
