Wouldn't "global" be a better word than "external"?  Anyway, global
variables default to being zero so they don't need to be initialized.

/* Error variable.  Zero means no error. */
int dt3155_errno;

But really this global variable is pretty ugly.  It would be better to
eliminate it.  You would have to modify wait_ibsyclr() somehow...
