I did a full compile of 2.4.8-pre3 for i386, after suppressing 117
config entries that generated error messages. Another mail will
contain the error information.
Even after removing all the code that will not compile at all, there
are still a lot of warning messages in 2.5.8-pre3. I offer this list
in the hope that the maintainers will fix the code (I can dream, can't
I?). No need to copy me on replies, just fix the code.

Looks like someone screwed up arch/i386/kernel/mpparse.c
between pre2 and pre3 - at a glance, it looked like someone
took an old version of the file without my changes to support
multi-quad PCI on NUMA-Q, and hacked it forward without changing
it properly ...

In looking at the changesets, it seems that the offending party is the
ACPI group. I'd go complain to them :)

Ah, this one shows up due to libfs now being in the kernel. I'll fix
it.

These linker errors should be fixed in 2.5.8 now.
