often it's the implementation for certain platform that limits you, choices of what the C++ supports decides by the platform vendor - for example exceptions, rtti, or even up to date compiler. another provblem arises due to the decoration, mangling of c++ symbols (while c externs do not have this problem), and sometimes this is problem even with two different versions of the same line of compiler another one is the runtime incompabilities (exceptions again) and different compilers. this problem is so bitchy, that if you have to develop plugin for maya, motion builder in c++, you have to use the same compiler the products were compiled with, which is not the case for a lot of the infrastructure, os out there...
