Description:
------------
If an interface defines a constant and is then implemented by a class
which is then extended with a further class and both classes implement
the interface, the second class may override the interface constant
without a fatal error. Also present in 5.2.10 on FreeBSD 7.2

Reproduce code:
---------------
---
From manual page: language.oop5.interfaces
---
http://codepad.org/vStYX1Kz

Expected result:
----------------
Fatal error:  Cannot inherit previously-inherited constant c from
interface ia ... on line 18

Actual result:
--------------
Program outputs "OceanSea" which indicates that the interface constant
is still available but the class constant with the same name overrides
it.
