I think this is an excellent idea.  (And yes, that's what
we're talking about!)

The dummy variable only needs to be defined on non-variadic and
non-VC systems.

BTW, is there a standard way to force a compiler warning message 
that this variable assignment is being used?  For example:
  #pragma message("warning: TRACE function using assignment.")
