>From which Fortran spec version is C1227? With all new code, we'd like to be explicit about what Fortran spec version a particular rule is from, e.g. `F'2003 C1227` (or whatever the version number).

Please modify all the `Cxxxx` you added in similar fashion, so that when F'2058 is a current spec we know where those specific `Cxxxx` come from :-)
