Testing showed that the finalization wrapper caused errors of the kind:
Error: The intrinsic '_F.rank' declared INTRINSIC at (1) is not
available in the current standard settings but new in TS 29113. Use an
appropriate -std=* option or enable -fall-intrinsics in order to use it.
That's fixed by the attached patch, which I have committed as obvious
(Rev. 199355). (I have a test case, which depends on a not yet submitted
patch. The artificial cannot interfere with user functions as GFC_PREFIX
gives a symtree which cannot interfere with a normal Fortran name.)
