Thanks to all those who responded to my question about cpp. In the case here
it only works if we use /bin/cc -E instead of /lib/cpp. That isn't exactly
what I want. If you wanna play with it and see if you can get it
to work (without using /bin/cc -E  or without passing an option
(like -Dprism) to cpp) then let me know. To run it you just type
                 Configure


This is a short version of the file Configure. Ideally it should not be 
modified.

#!/bin/csh -f
set cpp="/lib/cpp"
set system_line=`$cpp  <GetSystem | sed -e '/^#/d' -e '/^$/d'`
echo this is an $system_line[3] machine

This is the file GetSystem. You can make whatever changes you want to this file.

I would appreciate any changes you can make to the GetSystem file to
get this thing to return  "this is an Apollo10k machine".
Sorry about being picky about this but I wished Apollo had a cpp #ifdef 
just for the dn10k (see above for #ifdef's available on the suns).
