va_list isn't an actual type.  It is a macro that expands to some other 
type.  For x86, that is char *.  So when calling a C++ overloaded 
function, there is no way to distinguish between a va_list argument and 
a char * argument, as they are exactly the same thing.

The code you wrote isn't portable.  Whether it works depends on the type 
used for va_list by the target.  If the target uses a unique type for 
va_list, it will work.  Otherwise, it won't.
