+       * lisp.h (vcopy): Use memcpy rather than our own loop.
+       This fixes a performance regression introduced by the recent
+       addition of vcopy.  This means 'vcopy' will need to be modified
+       for a copying collector, but that's OK.  Also, tighten the
+       checking in the assertion.
