How to resolve the warning message during Out of Box (OOB) C code compilation?

---------------------------------------
In file included from fm_bill_pol_calc_pymt_due_t.c:18:0:
../../../include/pin_bill.h:129:14: warning: ‘not_billable_items’ defined but not used [-Wunused-variable]
static char *not_billable_items[] = {
^
../../../include/pin_bill.h:504:14: warning: ‘map_seq_id_to_name’ defined but not used [-Wunused-variable]
static char *map_seq_id_to_name[] = {
---------------------------------------
Static arrays from OOB pin_bill.h
static char *not_billable_items[] = {
};
static char *map_seq_id_to_name[] = {
};

Reproduced Steps:
---------------------------
i. Go to dir /pinhome/pin/opt/portal/7.5/source/sys/fm_bill_pol

ii. Run make. All goes fine.

iii. Backup Makefile in the dir and open the orginal Makefile file and append "-Wunused" like below:

    CFLAGS_linux= -m32 -fPIC -Wunused

iv. Remove the *.o files and fm_bill_pol_custom.so [if they exist].

    e.g rm -rf *.o and rm fm_bill_pol_custom.so

v. Run make again, can see the warning messages as below:

>> make
gcc -c -m32 -fPIC -Wunused -D_REENTRANT -DFOR_CM -DFM_BILL_POL_DLL
-I../../../include -DPCMCPP_CONST_SAFE -DFOR_CM -DFM_BILL_POL_DLL
