fortran/3743: Reference to intrinsic `ISHFT' invalid

Synopsis: Reference to intrinsic `ISHFT' invalid

State-Changed-Why:
    G77 does not recognize BIT_SIZE intrinsic as integer.  The
    implicit type for a function whose name begins with the
    letter 'B' is REAL, so G77 reports that a function returning
    basictypeREAL is not a valid argument to the ISHFT intrinsic
    expecting a basictypeINTEGER argument.  Declaring BIT_SIZE
    as INTEGER removes the error.
    It is unclear why this only fails on some targets.  BIT_SIZE
    does not seem to be recognized as an intrinsic when the
    arguments to ISHFT are examined, it considers BIT_SIZE a
    function returning REAL.  Is something non-deterministic
    in the parser?
