I don't own this device and stumbled upon this conversation by accident, but the "#undef COMBO_DEVICE_SUPPORTED" comment actually does make sense.

Line 40:
#define COMBO_DEVICE_SUPPORTED 0

Line 1346:
#ifdef COMBO_DEVICE_SUPPORTED

The "#ifdef" is only checking if the token has been defined - it doesn't matter if it's defined as "0" or "false" - it's still defined. I only noticed this recently when I noticed my unofficial galaxy5/tass ports were using parts of the combo code unexpectedly.
Line 1346 should really be: "#if COMBO_DEVICE_SUPPORTED".
