I tried the best I could with 4.7 but there are quite significant divergences
with trunk, both around and downstream from the patch.  The best that I could
manage was:

/svn/gcc-4_7-branch/gcc/testsuite/gfortran.dg/select_type_31.f03:16.4:

    select type (component => self%cb(i) ! { dg-error "has no IMPLICIT type" }
    1
Error: Unclassifiable statement at (1)
/svn/gcc-4_7-branch/gcc/testsuite/gfortran.dg/select_type_31.f03:17.7:

    end select
       1
Error: Expecting END FUNCTION statement at (1)

which is more opaque than the correct error followed by the internal error!

I decided, therefore, to leave the PR as 4.7 only and have unassigned myself.

In addition, I think that to call it a regression is incorrect since
polymorphic arrays were unavailable in 4.6!  I have therefore removed
regression from the title.

I might be persuaded to return to this, once 4.8 is released.
