 Message        <where> "<name>" <modifier>requires an integer
                register but its linkage "<name>" specifies a
                floating register.  Standard linkage will be used.

 Description    A parameter or return value of a function type is an
                integer type, but the corresponding parameter or
                return value in the special linkage specifies a
                floating register.  The special linkage was specified
                via the #pragma use_linkage directive.  Because of
                this mismatch, the compiler will ignore the special
                linkage and use the standard linkage instead.

 User Action    Make sure the register specified by the special
                linkage matches the type of of the corresponding
                parameter and return value of the function type.
