--- Comment #1 from Tobias Burnus <burnus at gcc dot gnu.org> 2013-04-30 16:44:36 UTC ---
For clarification:

- ABS and SIZE are both generic names, either having an intrinsic and a user
specific procedure.
- In "sub", the specific functions of "SIZE" do not match the rejected calls.
- The specific functions of "ABS" do match - and both have the same generic
name

See:
    USE MOO, ONLY: RENAME => ABS
    CONTAINS
        SUBROUTINE SUB
            USE MOO, ONLY: RENAME => SIZE, T


Thus, the question is whether the generic "rename" are merged or whether the
inner "rename" overrides the host-associated "rename".

If they are merged, the question is how ambiguity is handled.
