Invalid use of 'long'

[Gaurav Tanna <tannagaurav@xxxxxxxxx>]

Hi all,
I am compiling a benchmark program (Health - Olden benchmarks). The
following is a code snippet. (Its not possible to give the complete
benchmark)

#include <stdio.h>
#include <stdlib.h>
#include "health.h"
#ifndef PLAIN
#include "mem-ref.h"
#include "future-cell.h"
#else
#define MIGRPH();
#endif

int dealwithargs(int argc, char *argv[]) { 
  /*MIGRPH();*/
  if (argc < 5) {
    fprintf(stderr, "usage:  health <# levels> <time> <seed> <# proc>\n");
    exit(1); }
  
  max_level = atoi(argv[1]);
  max_time = atol(argv[2]);
  seed = atol(argv[3]);
  __NumNodes = atoi(argv[4]);
}

I am getting following errors and I am not able to understand why.
Please can anyone help me out.

Thanks very much in advance.
