Actually, unless gcc is compiled with -D_FILE_OFFSET_BITS=64, the error
would happen much earlier, particularly in open_file, open() would return
-EFBIG first.

  /* Don't issue an error message if the file doesn't exist.  */
  if (errno != ENOENT && errno != ENOTDIR)
    cpp_error_from_errno (pfile, filename);
