fix up option handling
After 79241696, the following anomalies came up: - --mac-compat and --read-only was rejected originally on server side, 79241696 cancelled this check - direct I/O option handling was interfered by 79241696 - --mac-compat had no effect on Linux and does not compile on Mac Restore original behaviors.
