There's nothing wrong with using va_list *, the only problem is when 
taking the address of a parameter to do so.

With a variable

va_list ap;

you use &ap to take the address.

With a parameter (subject to array-to-pointer adjustment)

  va_list ap

you use &ap if va_list is not an array type, but ap if it is an array
type.
