Well, they are part of Fortran 95 and later standards.

Which is irrelevant as gfortran started life with the ambitions
to be a Fortran 95 compiler. You'll note that there isn't a
-std=f90 nor -std=f77 mode. In fact, you'll find all intrinsic
procedures in the documentation that are listed in the Fortran
95 and that also appear Fortran 90 are listed as "Fortran 95
and later".

Yeah, this could use some word smithing. It appears
to be an attempt to discourage use of srand and rand
in favor of the standard intrinsic subprograms. You
also left out the most incorrect part of the documentation.
gfortran uses 4 independent KISS generators, but
implementation details should probably be removed
here.
