DFLOAT is a nonstandard intrinsic, but many compilers 
support it.  Can you file a bug report to support DFLOAT
as an extension?  To move forward with your code, you can 
make a global substitution of DFLOAT to DREAL.  Note, DREAL
is also an extension, but gfortran already supports it.
The correct Fortran 90/95 fix is to change DFLOAT(X) to
REAL(X,KIND(1.d0)).
