I think gfortran is correct when rejecting the intrinsic functions in
Table 13.3: Restricted specific intrinsic functions
(Fortran 2015 draft).

I did not find such wrong codes, however I have opened pr68433 for wrong codes
when including the optional argument in the interfaces.

If so, I think it deserves a separate PR.
