  But will va_arg necessarily work when va_copy is just a memcpy
  (at least in the case where va_end is *not* empty)? This seems
  optimistic.

A good question.  This is old code, and I don't know how broadly it was
tested outside the realm of gcc.

To check this, we'd need some environments with just a c90 compiler
which also does not provide va_copy as a courtesy.
