How to write a c++ assert macro with a varying number of informational arguments?

Question

I am trying to write a macro dbgassert similar to the standard assert. In addition to what assert does, I want to dbgassert

You have to write the contents of the function __assert - if you specified it's extern you should attach the file that contains the function's definition to the compilation process. If you don't know how to write a multiple-file program, I can't really help you.
