C++: fix handling of empty va_args macro arguments.
Preprocessor did not correctly handle when variadic macro arguments were not
provided at all, if there were other arguments: macro was not expanded
in case only the non variadic arguments were given.
#define MACRO(...) used to work fine for 0 or more arguments.
#define MACRO(ARG0, ...) used to work only for 2 or more arguments, now fixed.
