* include/ext/stdio_sync_filebuf.h
(stdio_sync_filebuf::_M_unget_buf): Declare it.
(stdio_sync_filebuf::stdio_sync_filebuf): Initialize _M_unget_buf.
(stdio_sync_filebuf::uflow): Store the returned character in
_M_unget_buf.
(stdio_sync_filebuf::pbackfail): If argument is eof(), pass
_M_unget_buf to syncungetc(). Set _M_unget_buf to eof().
(stdio_sync_filebuf<char>::xsgetn): Store last read character in
_M_unget_buf, if any, else eof().
(stdio_sync_filebuf<wchar_t>::xsgetn: Store last read character in
_M_unget_buf, if any, else eof().
