The stackoverflow suggests it is possible for MSVC.

Thinking about it some more I think what I'm suggesting is the wrong
approach. If you're writing C++ code you should avoid coupling your
classes to allow dependency injection (i.e. you pick how classes are
coupled at run time not at compile time). If your classes are written
with dependency injection in mind then you don't need the weak symbol
stuff I was talking about.
