Zaak,

AFAIK, yes, the change will only be made in the 8.0.  
We try very to maintain backwards compatibility with older
versions of gfortran, which means we seldomly break the ABI.
However, for 8.0 the introduction of user defined type IO
required a change to the ABI, so we (well mostly Janne and
Thomas) are trying to get other ABR breaking changes into
trunk.

Janne, can you provide Zaak where you think he may need
to check OC's ABI against your change?
