As I said, I don't see how to do it in pure C++. But if we go away from pure C++ macro, if you use a code generator / custom preprocessor (modifying boost.wave?), it seems quite feasable, and in a very portable manner.  Personnaly I think a code generator would do the trick without difficulties (use boost.spirit to roll it quick!).

Eg : 
struct X
{
TRACK(NameOfTheMacroToTrack)

fn()
{
NameOfTheMacroToTrack(X,Y,Z))
}

TRACKEND(NameOfTheMacroToTrack)
};

Seems ok, isn't it? I think with only the first TRACK it is even possible to do it easily. - Be sure to ignore comments thought -.
