 Message        The CDD description for <name> specifies the
                D_Floating data type.  The data can only be
                represented when compiling with /FLOAT=D_FLOAT.

 Description    The /FLOAT command-line qualifier specified a
                floating type other than D_floating format.  The CDD
                description specified was D_floating type, which did
                not match the floating type specified on the command
                line.

 User Action    Specify the correct command-line qualifier, or change
                the description of the item in the CDD.
