Thanks. I tried again with the .owner patch applied to prism2_usb.c as
per that message, however this only reduced the build log from 11683
lines to 11680. To investigate further, I saved a log of a successful
build on kernel-2.6.14-1.1656_FC4 and compared with the failed 2.6.16
build. It turns out that the first set of errors that I posted...

...occur in the successful build, too. Hmm. The first point at which
the builds diverge is here:

I.e. the CC lines for p80211mod.o etc are absent from the 2.6.16 build;
there are no references whatsoever to p80211mod.o etc in the log.

I expect that someone who's familiar with the source will pick up
what's happening a lot more quickly than I could, so over to the
experts! Let me know if a complete build log would be helpful.

Cheers,

Dave
