@costumeitem equip issue

[Lelouch vi Britannia]

After upgrading my trunk into the latest git this error shows up...

script.c: In function ‘buildin_costume’:
script.c:21369: error: ‘equip’ undeclared (first use in this function)
script.c:21369: error: (Each undeclared identifier is reported only once
script.c:21369: error: for each function it appears in.)
make[1]: *** [obj/script.o] Error 1
make[1]: Leaving directory `/root/Desktop/rathena/src/map'
make: *** [map] Error 2

After searching it was on...

if (num > 0 && num <= ARRAYLENGTH(equip))

and this is the whole src

/**
 * Costume item edit
 **/
BUILDIN_FUNC(costume) {
	int i = -1, num, ep;
	TBL_PC *sd;

	num = script_getnum(st, 2); // Equip Slot
	sd = script_rid2sd(st);

	if (sd == NULL)
		return 0;
	if (num > 0 && num <= ARRAYLENGTH(equip))
		i = pc_checkequip(sd, equip[num - 1]);
	if (i < 0)
		return 0;

	ep = sd->status.inventory[i].equip;
	if (!(ep&EQP_HEAD_LOW) && !(ep&EQP_HEAD_MID) && !(ep&EQP_HEAD_TOP))
		return 0;

	log_pick_pc(sd, LOG_TYPE_SCRIPT, -1, &sd->status.inventory[i]);
	pc_unequipitem(sd, i, 2);
	clif_delitem(sd, i, 1, 3);
	// --------------------------------------------------------------------
	sd->status.inventory[i].refine = 0;

	sd->status.inventory[i].card[3] = GetWord(battle_config.reserved_costume_id, 1);

	if (ep&EQP_HEAD_TOP) { ep &= ~EQP_HEAD_TOP; ep |= EQP_COSTUME_HEAD_TOP; }
	if (ep&EQP_HEAD_LOW) { ep &= ~EQP_HEAD_LOW; ep |= EQP_COSTUME_HEAD_LOW; }
