That helps a lot.  It would be even better if at the start of the configure 
checks the output could read something like:

Running configuration checks
Some cached configure checks were found, run with --reconfigure to force 
these to be rebuilt.

Then we don't have to go hunting around in docs for the command line option, 
and folks that haven't seen this discussion won't be out in the cold.

Just my 2c worth, John.
