+   <sys/gentape.h>.  SCO and BSDi uses <sys/tape.h>; BSDi also requires
+   <sys/tprintf.h> and <sys/device.h> for defining tp_dev and tpr_t.  It
+   seems that the rest use <sys/mtio.h>, which itself requires other files,
+   depending on systems.  Pyramid defines _IOW in <sgtty.h>, for example.  */
