man g77
[...]
       -ff90
           Allow certain Fortran-90 constructs.

           This option controls whether certain Fortran 90 constructs are
           recognized.  (Other Fortran 90 constructs might or might not be
           recognized depending on other options such as -fvxt,
           -ff90-intrinsics-enable, and the current level of support for
           Fortran 90.)
