DCLMISMATLNK5

Message        "<name>" has a void return type but its linkage
               "<name>" specifies a return location.  Standard
               linkage will be used.

Description    If a special linkage specifies return value
               information, the declaration must not specify a void
               return type.  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 return value specified by the special
               linkage matches the return type.
