Just in case... oh, i see. i should make myself clearer. i'm talking about #ifdef __CYGWIN__ int cv[2]; #endif in rshd.c. base implementation uses pipe to handle stderr, but cygwin version seems to handle stdout via pipe too. if some program started by rshd then calls getpeername (1, &name, &name_len), it fails with ENOTSOCK. i suspect there was some reason for adding 'cv', wasn't there?
