DCLMISMATLNK3

Message        <where> "<name>" has a size that is incompatible with
               the number of registers specified by its linkage
               "<name>".  Standard linkage will be used.

Description    The size of a parameter or return value of a function
               type is incompatible with the size specified by the
               special linkage.  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 number of registers specified by the
               special linkage match the type of the corresponding
               parameter and return value.
