gcc solves this problem by requiring submitting the change upstream  
and only changing the file from the upstream directly.  Those changes  
(a slightly different spelling by a different author) are now in  
progress going in upstream, but, last I knew, there are not in yet.   
If an update to a fixed autoconf version could undo a config.guess  
change, trivially, config.guess can't by changed by an autoconf  
upgrade. if we are to retain modifications to this file and ever have  
changes to the file.
