per1234	86115884c7	Make preprocessor conditional false when identifier undefined A preprocessor conditional directive intended to only evaluate as true when compiling for the Arduino Nano 33 BLE board was also evaluating as true when compiling for any board that didn't define the compared identifiers because undefined identifiers are replaced with 0 by the C/C++ preprocessor, making them equal. From the C++11 standard section 16.1, paragraph 4: > After all replacements due to macro expansion and the defined unary operator have been performed, all remaining identifiers and keywords 148 , except for true and false, are replaced with the pp-number 0 The fix is to modify the directive to check whether the macro has been defined.	2020-12-01 17:53:54 -08:00
