Well, certainly work that is PD would not have a copyright header,
because it wouldn't be in the public domain if it was copyrighted.
However, a copyrighted work doesn't have to have a copyright header. So,
you definitely cannot say a work without a copyright header is public
domain.

(There is some dispute over whether or not it is possible to renounce
your copyright and put a work into the public domain; it varies by your
region. Works whose copyright have expired are definitely PD, but that
is unlikely to cover any computer code ;)

Cheers,

Alex.
