#9 utarray warning with -Wextra option complier

[Anonymous]

Hi, it is a nice tool. However, can you fix some warning from -Wextra option compile

gcc -Wall -Wextra -std=gnu99 ./test1.c -o test1
./test1.c: In function ‘main’:
./test1.c:20:3: warning: comparison of unsigned expression < 0 is always false
./test1.c:23:24: warning: signed and unsigned type in conditional expression
./test1.c:23:24: warning: signed and unsigned type in conditional expression

My code is here :
#include <stdio.h>
#include "utarray.h"

UT_icd utarray_unit_icd = {sizeof(unsigned), NULL, NULL, NULL };

int main() {
UT_array *nums;
UT_array *numsToAdd;
unsigned l, *p;

utarray_new(nums, &utarray_unit_icd);
utarray_new(numsToAdd, &utarray_unit_icd);

l=1; utarray_push_back(nums, &l);
l=2; utarray_push_back(nums, &l);

l=3; utarray_push_back(numsToAdd, &l);
l=4; utarray_push_back(numsToAdd, &l);

utarray_inserta(nums, numsToAdd, 0);

p=NULL;
while( (p=(unsigned*)utarray_next(nums,p))) printf("%u\n", *p);

utarray_free(nums);
return 0;
}

Thanks and good job !
