Arduino 1.8.13 with Board Manager installed ESP8266 Community 2.7.2 does not understand:

#ifndef SDA
#define SDA (digitalPinToPinName(PIN_WIRE_SDA))
#endif
#ifndef SCL
#define SCL (digitalPinToPinName(PIN_WIRE_SCL))
#endif

If the instructions are removed, it compiles and works.
It appears that #ifndef does not recognize SDA and SCL.
When it tries to define SDA and SCL with digitalPinToPinName it throws an error.
