No need for the #ifdef CONFIG_Q40 - Q40 is the only m68k subarch that
builds the parport_pc module (which includes parport.h), IIRC. Is that

Thanks indeed for the link, Geert. I haven't yet had time to test
whether the io.h patch would interfere with Atari IDE or other drivers's
use of these macros - maybe this weekend.

I think Thorsten submitted a patch to that effect? If so, yours should
not be necessary.
