Not sure - I'll try playing around with it when I next have some spare 
time.. :)

The C-Mock extension (https://github.com/hjagodzinski/C-Mock) for GMock 
uses some dynamic linker trickery which I'm guessing is probably not C++ 
specific, and I quite like that approach as it avoids the need to 
pre-specify in makefiles which functions are to be mocked.
