GatewayESP8266 and GatewayESP32 do not compile with MY_USE_UDP

[mfalkvidd]

On 2.1.1, using the vanilla GatewayESP8266 sketch and uncommenting
#define MY_USE_UDP
and either uncommenting
#define MY_CONTROLLER_IP_ADDRESS 192, 168, 178, 68
or adding
#define MY_CONTROLLER_URL_ADDRESS "http://192.168.0.101"
results in compile error:

This might be related to #918

[mfalkvidd]

RWoerz has posted a suggested fix in https://forum.mysensors.org/post/78210

[mfalkvidd]

This error is still reproducible when using ESP8266 board definition 2.4.0 so it might not be related to #918 Or maybe it is related, but the problem has not been fixed in the ESP8266 board definitions yet?
