I have no idea where I got that from; it should have been __rwelision.

Thanks, committed.

    Fix build warning in pthread_rwlock_*
    
    The first argument of elision_adapt and that of ELISION_*LOCK have
    different signs since __elision_rwcount is signed char * and the
    argument of elision_adapt is uint8_t *.  Modified elision_adapt to
    accept signed char * instead of uint8_t *.
