I found a way around all VC++ bugs regarding variadic macros and
__VA_ARGS__. You can retrieve any single token from the variadic data
using my library, whether in VC++ or any other compiler supporting
variadic macros.

The library is in the Boost sandbox in the variadic_macro_data
directory, and it already comes with full documentation there, both html
and PDF. All you have to do is checkout using SVN from the sandbox
directory.
