It's not possible, as all macros are removed in the first pass of the
compiler and don't make it into the shared library at all.  For something
like this you need SWIG, which processes the source code.

Consider the matter of Analytic Philosophy.  Dennett and Bennett are well-known.
Dennett rarely or never cites Bennett, so Bennett rarely or never cites Dennett.
There is also one Dummett.  By their works shall ye know them.  However, just as
no trinities have fourth persons (Zeppo Marx notwithstanding), Bummett is hardly
known by his works.  Indeed, Bummett does not exist.  It is part of the function
of this and other e-mail messages, therefore, to do what they can to create him.
