Right.  I'm sorry, I meant to imply a libiberty macro.  Something
like:

  #ifndef va_copy
  #define va_copy(DEST, SRC) \
     memcpy (&DEST, &SRC, sizeof (va_list))
  #endif

would probably do the trick, after including the right header files.
Perhaps this should go in system.h instead; I'm not sure whether
including the <stdarg.h> stuff in libiberty.h is a good idea or not.
