Use the preprocessor directives for conditional compilation.

B4R: 
Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'Public variables can be accessed from all modules.
    Public Serial1 As Serial
    Private Result As Int 'ignore
End Sub

Private Sub AppStart
    Serial1.Initialize(115200)
    Log("AppStart")
    RunNative("Function", Null)
    Log("Result: ", Result)
End Sub

#if C

#define def_2
// #define def_1
#ifdef def_1
void Function (B4R::Object* o) {b4r_main::_result = 1;}
#endif
#ifdef def_2
void Function (B4R::Object* o) {b4r_main::_result = 2;}
#endif
#End if

Thank you. will try tomorrow. I've tried according to Arduino C syntax, with no success...

It works. I don't know how many tries with syntax I have done ! Thank you thetahsk!

Just so that I can understand - why is #define def_1 commented out above? What will happen if #define def_1 is uncommented?

You see that the inline C calling functions have both the same name , but returns different values.
So you can decide which function to use.
If both def_1 and def_2 are defined, the compiler didn't know which function to use and creates a redefinition error.
