I do not see that.

$ type ts1_90.f90
! this should not compile with Fortran 77
program ts
    real (kind=4) x
    x = 123.456
    call f(x)
end
$ type ts2_90.f90
! this should not compile with Fortran 77
subroutine f(x)
    integer (kind=4) x
    print *, x
end
$ for /warn=all ts1_90
$ for /warn=all ts2_90
$ link ts1_90 + ts2_90
$ run ts1_90
