Parsing header files is out of scope. It is a programming language and can be quite complex if you do not just add values after the #define statements. It could be computations with other macros, ...

#define X_BED_SIZE 235

#define EXT2_ENABLE_PIN ORIG_E2_ENABLE_PIN

Okay, first i deactivated line 310 #define ENDSTOP_Z_BACK_ON_HOME 0. It issued a so called: "Compilation error: 'DIOFAN2_PIN_WPORT' was not declared in this scope"
