That is a new feature in C99, so its not all *that* surprising that VC++ 
doesn't support it, after all its only 2002.

Might try using the older syntax for vararg macros:
#define CALLN(args...) _CALLN(regs, args)
I have no idea if that's supported, but its worth a try. Or maybe they 
use yet another syntax...could be worth looking through the 
documentation.
