First of all Zortech's C++ is only targeted (as far as I know) for the intel iapx80x86 family of processors running OS/2 and MS-DOS. Unless it has been retargeted for the 1750 or some other popular flight qual'd processor I would doubt that this comparison makes any sense. The second thing is that the run time efficiency of the code can not be compared to the compile speed...just to the code generation quality! Third thing is that in an embedded system maybe due to less overhead some certain implementation of a c++ compiler will beat some certain implementation of an Ada compiler to handle an interrupt (although since c++ doesn't have a builit in ability to handle interrupt, it will have to be done partially outside of the language). But, if they are both able to answer to interrupt within the required maximum latency then everything is peachy with both implementations! And we all know which one it is easier to write code in....
