+       * engine-gpgsm.c (iocb_data_t): Add SERVER_FD_STR.
+       (gpgsm_new): Set it.
+       (gpgsm_set_fd): Use it.
+
        * w32-glib-io.c (find_channel): Add a new primary flag.
        (_gpgme_io_close): Close channel only if primary.
        (_gpgme_io_dup): Put newfd into the table as shallow copy.
