vlsi_ir.h in 2.4 and 2.5 differ significantly, and I therefore suggest the
following patch to remove the compatibility stuff that caused this problem
(IMHO a better solution than an #include <linux/version.h>):

Thanks for the report. I personally don't care too much for
this compatibility code, so the patch is OK to me. Martin ?

Thanks for doing these tests. Unfortunately I've never seen this problem
before. Might be it's because the whole linux-irda system is assumed to be
build as module and I've almost never tried compiling it into the kernel.
Anyway, of course I agree with you the stuff must not break compiling.
It looks like you are right, there's a linux/version.h missing in the
includes. Does this solve the issue for you (it does for me)?

The 2.5/2.4 differences are only temporarily there and due to the usual
approach to apply new stuff to 2.5 first before moving into 2.4. The
current 2.5 code should go into 2.4 rather soon and there will be further
changes along this path. So the compatibility defines are there for a good
reason and the very few differences between 2.4 and 2.5 (wrt. this
driver) do not justify the increased effort of having two versions.

If this gets removed I can assure you the driver won't compile ;-)
Please apply the following fix.
Thanks
Martin

yes, this fixes it.
Alan:
You did already include my patch into -ac. Please remove my patch to
include/net/irda/vlsi_ir.h from -ac and include Martin's patch (at the
bottom of this mail) instead.

You are right, this was surrounded by so much comment that I assumed it
was a comment, too...
Unfortunately the file compiled with a "implicit declaration of function
`pci_dma_prep_single'" and since the .config I was using is far from
getting to the final linking stage I didn't notice the problem...
