The easiest way to disable code (without removing it) is to just remark it out:

bool EQEmu::ItemData::IsEquipable(uint16 race_id, uint16 class_id) const
{
	//if (!(Races & GetPlayerRaceBit(race_id)))
	//	return false;

	if (!(Classes & GetPlayerClassBit(GetPlayerClassValue(class_id))))
		return false;

	return true;
}

Also, TortoiseGit is a great menu-driven git tool that saves a lot of headaches.
