** NAME:        dev_printf
** SYNOPSIS:    int dev_printf(const char far *fmt, ...)
**              const char far *fmt;    format specifier as printf,
**                                      see format() for more details.
** DESCRIPTION: Printf() equivalent for a device driver at init time.
**              The use of this function at non init time is absolutely
**              forbidden since it will call DosPutMessage.
** RETURNS:     As printf()
