* fhandler_termios.cc (fhandler_termios::sigflush): Avoid SEGV in pathological
condition of get_ttyp() == NULL.

the existing contents of sem, so merely warn rather than return EBUSY
if it looks like we are reinitialising a semaphore.

* environ.cc (regopt): Use wide char arguments in reg_key functions.
* fhandler_console.cc (beep): Ditto. Use WCHAR throughout.
