Ivan Grokhotkov 3f8d9d71e2 lwip: fix duplicate definition of O_NONBLOCK ... LwIP will define O_NONBLOCK in sockets.h if it isn't defined yet. If sys/fcntl.h is included after socket.h, there will be duplicate definition. Work around by including sys/fcntl.h into lwipopts.h. https://github.com/espressif/esp-idf/issues/75		2016-11-08 20:17:08 +08:00
