Yes.

REAL(4) is single precision and REAL(8) is double precision.
Note, gfortran is going to be backwards compatible with g77,
so the REAL(1) and REAL(2) enumerated kinds will need to be
supported at some point.  I don't know if this will be done
as a compiler option.  I doubt gfortran will support 8 and
16 bit REALs, so mapping REAL(1) to REAL(4) and REAL(2) to
REAL(8) should be straight forward (famous last words :).
