Of course I have cpp installed, but once more, it is not in /lib/cpp, but 
in /usr/bin/cpp. This is the standard location on all Linuxes I've ever 
seen (Debian, RH, SuSe, Scientific, ...).

Unfortunately this cannot be the solution (since I definitely have cpp and 
as I already mentioned, I temporarily solved the cpp problem by changing 
the /lib/cpp to /usr/bin/cpp in above Makefiles, no other changes).

I tried to run the find through the whole filesystem to look for all *.h 
files containing AFSFid, but didn't find anything. I have two identical 
systems with the only difference, and it is the kernel tree. I am building 
fine on system with PENTIUMM and got these errors on ATHLON (these are the 
major differences, but I have no idea if relevant or not), both 
linux-2.6.18.

Thank you in advance for other suggestions and help.
