This is not necessary; the parent's spec (including the private part)
is directly visible within the child.

Though I'm not sure what help that would be in future, since in 4.3.0
the spec is ..

   with System.Regpat;

   package GNAT.Regpat renames System.Regpat;

But the only private type in Regpat is Pattern_Matcher. Is knowledge
of Pattern_Matcher required in order to write OP's extensions? If so,
OP will have to write a child (of System.Regpat, I think).
