UDP enum conflicts with arduino samd core libraries

[xadhoom]

Hello, seems that there's a naming clash between an internal UDP constant and arduino core libraries:

here's the errror:

exit status 1

Compilation error: exit status 1

the sketch is very basic, just

#include <Sodaq_R4X.h>
#include <Sodaq_Ublox.h>

in a empty sketch

Any hint?
