     40  * This header defines the va_copy variable argument macro, which is
     41  * new in ISO C 1999, and thus not present in ISO C 1989 and ISO C++
     42  * 1998.  Because this macro is a long-standing Solaris extension, it
     43  * is also permitted in other contexts.
     44  *
     45  * The varargs definitions within this header are defined in terms of
     46  * implementation definitions.  These implementation definitions reside
     47  * in <sys/va_list.h>.  This organization enables protected use of
     48  * the implementation by other standard headers without introducing
     49  * names into the users' namespace.
