This now compiles on ESP platform v2.4.2 and v2.5.2 on Arduino IDE 1.8.9 and 1.9.0 beta. I've also uploaded to example to ESP8266 to double check and works fine.

|
* No memory is consumed in the sketch if your code does not call any of the string methods
|
|
* You can change the text of the strings, make sure the short strings are each exactly 3 characters
|
|
* the long strings can be any length up to the constant dt_MAX_STRING_LEN defined in TimeLib.h
