Is this standard Fortran 2008?

Is this code standard Fortran 2008?

MODULE PRECISION
IMPLICIT NONE
INTEGER,PARAMETER :: DP = 8
END MODULE PRECISION
MODULE M
USE PRECISION
IMPLICIT NONE
INTERFACE
    REAL(KIND=DP) MODULE FUNCTION F(X)
        REAL(KIND=DP),INTENT(IN) :: X
    END FUNCTION F
END INTERFACE
END MODULE M

I have another compiler who complains that DP in the "REAL(KIND=DP) MODULE FUNCTION F(X)" statement is not defined.
