Well, Derrick is on vacation, so I'm going to channel him...

Please send the output of 'dpkg-query -l cpp'

If there's no /lib/cpp, then you have a problem.  Fix the problem, instead 
of trying to argue with me about filesystem policy or, worse, history.  If 
your unix experience is limited to four relatively recent Linux 
distributions, you don't have enough of a sample to say what the "standard 
location" is of anything as old as the C preprocessor.

Did you try?

Well, if you'll recall, I said:

>> The AFSFid type is defined in src/fsint/common.xg.

Note that file does not have a name ending in ".h".
I also explained how afsint.h is generated from afsint.xg, which includes 
common.xg, and how that's not working because rxgen expects to run /lib/cpp 
and you don't have one.  Provide it, and your problem will go away.
