warning: `cleanup' attribute directive ignored

[Justin Cinkelj <justinc@xxxxxxxxxxxxxxxxx>]

Can somebody tell me how to use __attribute__ cleanup?

Here is my (not working) code:
#include <stdio.h>

void cleanup_int(int *pInt)
{
  printf("Cleaning %d\n", *pInt);
}

int main()
{
  int count __attribute__ ((cleanup (cleanup_int)))=3;
  int ii;
  for(ii=0; ii<count; ii++)
    printf("ii = %d\n", ii);
  return 0;
}

And output from the console:
[justinc@cepin gcc_cleanup]$ make && ./test_cleanup
gcc test_cleanup.c -o test_cleanup
test_cleanup.c: In function `main':
test_cleanup.c:11: warning: `cleanup' attribute directive ignored
ii = 0
ii = 1
ii = 2
