Come on, you cannot even link C++ shared libraries from different version of standard library, potentially also compiler. ABI compatibility in C++ does not exist.

In C, you still had incompatibilities between compilers. (MS fastcall convention and declspec come to mind...)

There's better ABI compatibility than in the languages where you have to rebuild after every minor version bump. The C++ standard library version (and to some extent, the compiler) should be considered part of the platform.
