Eric, sorry if I misled you. Someone had said pointer tags were _never_
maintained if you copied something containing a pointer to a character
field, and I said that this non-copying of pointers was not guaranteed,
but that in fact, occasionally the character field would indeed contain
a valid pointer.

What you are doing _is_ supported. If you copy one structure to
another, and they are both defined to contain pointers, then the
pointers will always be preserved when you copy back and forth
between the structures.
