row0mysql.c:

  If one tries to drop an InnoDB table without an .ibd file, print to .err log that we DID remove the table from the internal data dictionary of InnoDB, and return DB_SUCCESS so that MySQL will delete the .frm file; the drawback in this is that then DROP TABLE returns success, and the user is not alerted; maybe it could return a warning
