C++ and C

[Reinhard Doelz]

Hi , 
we are about rewriting our graphics application in order to tune code. 
We have some own object-oriented modules which would fit 
pretty nicely in C++ structures. However, as tuning is the 
ultimate target, does anyone know about 

*   C++ performance in comparison to 'plain' C modular structures

*   possibility to complile/link/debug/pixie C++/C mixed code 

*   Optimizer issues: problems with O3?

*   System resources: more than 'usual' - ? (We got only 16 megs on a 120).

*   C++ and power vision calls 

I'd appreciate any hints. 
Regards, 
Reinhard
