Bug description:signature incompatibility warning when used with interfaces

Description:
------------
hi, test this:

interface A {}
interface X { public function __construct(A $x); }

class A_BASED implements A {}
class X_BASED implements X { public function __construct(A_BASED $x){} }


interface X says that the first parameter of the constructor must be
instanceof A

X_BASED implementation has a constructor with first parameter A_BASED

so, this warning is not correct:

Fatal error: Declaration of X_BASED::__construct() must be compatible with
that of X::__construct()

because

"A_BASED implements A"
