* src/rtl/hbinet.c
    * Do not set SO_EXCLUSIVEADDRUSE on Windows in
      HB_INETSERVER(), HB_INETDGRAMBIND() calls.
    ; NOTE: INET API is compatibility API, it's deprecated and
            not recommended. Use SOCKET API instead, where
            you have full control of above options and it's
            also much superior API.
