integrating c++ files into NIOS II

While a small subset of C++ might be useful in an embedded system (simple inheritace), but the sheer amount of code generated for templates, exceptions and stream io will cause issues, never mind problems with heap space.

Rather like the fact that you CAN run linux on the nios (with external DDR memory), doesn't necessarily mean that it is a good idea to do so - unless your processing requirements are limited and you have fpga resources going to waste.

(Someone will probably shout me down on that one!)
