Re: Remove config.cache files when reconfiguring at top level

Ah - I did not know that users would ever modify the cache files.  Given 
that they do though - is it right that they should expect their changes 
to be preserved across a reconfigure ?  I would have thought that the 
cache files would have the same status as Makefiles - OK to modify for 
temporary local changes but never expected to last for very long.
