Suggest that srand and rand be replaced by random_seed and random_number

[Beliavsky]

For this code from the gfortran documentation, Fortitude could suggest that srand and rand be replaced by random_seed and random_number.

program test_rand
  implicit none
  integer,parameter :: seed = 86456
  call srand(seed)
  print *, rand(), rand(), rand(), rand()
  print *, rand(seed), rand(), rand(), rand()
end program test_rand
