Well, it likes Compaq's Tru64 UNIX compiler has a bug.  Sun's Forte C compiler
and gcc (each in ANSI mode, gcc with -Wall) complain about this code. Compaq's
compiler (in ANSI mode: -std1) does not:

#include <stdio.h>

int main () {

  int i = 0xFFFFFFFF; /* Here is where the complier squawks. */

  long j = i;

  printf ("i = %d, j = %ld, %d\n", i, j, sizeof (int) );

  return (0);

}

Thanks for pointing this out.
