> vsnprintf on Windows (visual) return -1 on failure instead of amount of bytes 
> needed.
> so line like this:
> int need = vsnprintf(stack_buf, STACK_BUF_SIZE, message, ap);
> won't work.
> Solution: ugly conditional compilation which will use microsoft specific 
> functions... See patch for details.
