Some warnings from compiler

[softy2k]

Hello !
I apologize if this is wrong place to put it here.
When I compile with last version of ArduinoIDE 1.8.8 I receive some warnings, like :

....\libraries\ICSC-master\ICSC.cpp: In member function 'boolean ICSC::process()':
....\libraries\ICSC-master\ICSC.cpp:323:59: warning: comparison is always false due to limited range of data type [-Wtype-limits] _commands[i].commandCode == ICSC_CATCH_ALL )

I ignore this message, I just wanted to point this out.
