  int main(int argc, char **argv)
  {
    int index;
    char resolvedpath[1000];

    for(index = 1; index < argc; index++)
    {
      if(realpath(argv[index], resolvedpath))
        printf("%-20s -> %s\n", argv[index], resolvedpath);
      else
        printf("%s: none\n", argv[index]);
    }

    return EXIT_SUCCESS;

  }

when i call this program with a filename that doesn't exist, index
gets overwritten with zeroes and the for loops forever!

if i declare resolvedpath to be at least PATH_MAX characters, though,
all is well.  the manpage didn't mention this, however.  am i doing
something wrong?

     #include <sys/param.h>

     char *realpath(file_name, resolved_name)
     char *file_name;
     char resolved_name[MAXPATHLEN];

which I would take as a clear indication that I cannot pass just
any sized buffer as "resolved_name".
