Really??  Again, I'm not really a C++ person, but have seen this syntax 
without std:: lots of times, and it's in the create-comp-config.sh 
script provided by cxx.  Oh well, must not have been ANSI-compliant 
code; I'm happy to have the .deb patch create-comp-config.sh before 
running it.

Hmm, just compiled with std::cout and std::endl, and got even more 
undefined symbols...

Can you tell me the steps you went through to get this installed?  I 
know you didn't (merely) use the .deb, because that would have put paths 
to 2.95.4 in your comp.config.

Thanks for your help!
