Lint's usefulness is too often underestimated. Whenever a program does not
produce the results I expect, the first thing I'll do is use lint. I cannot
stress this enough! USE LINT
cat tst.c

main()
{
  int i;
  i=5;

  (void)printf("\n%d %d\n",++i, ++i);
  return 0;
}

lint tst.c
tst.c
==============
(6)  warning: i evaluation order undefined
