MISMATPRSRET

Message        "<name>" has a non-void return type but its linkage
               "<name>" preserves the return register(s).  Standard
               linkage will be used.

Description    The function or typedef's special linkage specifies
               that the register(s) used to return the function
               value are to be preserved.  This is invalid as the
               register can either be preserved, or hold the return
               value, but not both.

User Action    Modify the #pragma linkage directive to either remove
               the register from the preserved list or to specify
               another register to hold the return value.
