15.3.26 Bit Operations on Floating-point Data

g77 does not allow REAL and other non-integral types for arguments to intrinsics like And, Or, and Shift.

For example, this program is rejected by g77, because the intrinsic Iand does not accept REAL arguments:

     DATA A/7.54/, B/9.112/
     PRINT *, IAND(A, B)
     END
