You still have to compile something!

As a long time Unix programmer, I am very familiar with function 
interposition.

The same rules apply to C++, but there in an extra layer of complexity 
in the form of name mangling.  In order to interpose a C++ function, you 
have to know it's mangled name.  That name will be compiler specific.
