Method (2) works, and it's not *too* clumsy /-:

8< ---- from `gpc.c' (essentially `gcc.c' from gcc-2.8.0) --------------

  /* Choose directory for temp files.  */

  temp_filename = choose_temp_base ();
  temp_filename_length = strlen (temp_filename);

#ifdef GPC
#ifdef __MSDOS__
  /* Ensure that `temp_filename' is really unique by
   * creating a dummy file of that name.
   */
  {
    FILE *kludge = fopen (temp_filename, "wc");
    fclose (kludge);
    record_temp_file (temp_filename, 1, 0);
  }
#endif
#endif

  /* Make a table of what switches there are (switches, n_switches).
     Make a table of specified input files (infiles, n_infiles).
     Decode switches that are handled locally.  */

  process_command (argc, argv);
