Hi!

If anyone has the hardware to play with PCMCIA, I have made this short patch
which will make you able to at least compile the PCMCIA package.
There are still some issues to be done, e.g. irq has to be always stored in
an int and not in a char and stuff like that, but as I don't know if anybody
is going to at least try it, I'm stopping here. Another issue is whether we
want 32bit programs to work with the PCMCIA ioctls or not. If we just allow
64bit cardmgr etc., it will be much easier.
The patch is against pcmcia-cs-3.0.5:
