Hello all,
I'm trying to come up with a solution for the following problem.

I've a macro with three arguments, but if the third is not given, it should
be assumed as '0'. Something on the lines of default arguments for
functions.

I'm using VS2005, and g++ 4.4.x so i can use Variadic macros, but I'm unable
to come up with a solution. Is there any way i can achieve this using
Boost.Preprocessor ?

I tried using BOOST_PP_IF but unable to proceed further. Any Ideas ?
