Since I've updated Arduino IDE this message appears repeatedly while I compile:
this use of "defined" may not be portable [-Wexpansion-to-defined]
I have seen that last gcc versions have stricter rules for define(name). Also I have found that with -Wno-expansion-to-defined you can disable that warning but I don't know, within Arduino IDE, I have to type it.
Is it possible? How I do it?
Thanks in advance for your response.
