see discussion here: esp8266/Arduino#4080
There it says:

The newer lwip solves more issues than it creates...

LWIP for ESP8266 repo is here: https://github.com/d-a-v/esp82xx-nonos-linklayer/tree/arduino-2.4.0
The issue they meant is esp8266/Arduino#3362

I think we should adapt it. You may have noticed that I do like to keep the ESPMega branch compiling with the latest core. I am aware of the fact that this is experimental and things may not work. Therefore the #ifdefs.
If you think I am messing things up around here please let me know :-)

Ahh thanks. Well this is the espeasy development branch and i expect everything to migrate to core 2.4 anyway. So thanks:)
