Interesting, I thought I had the build working for everything up to at
least 2.6.21.

Ah, I never tried the 2.6.19.x series, just checked the logs in gitweb
and don't really see anything that may have broken the headers like
this. I'm assuming it is something simple where we are simply not
including some required header.

Can't seem to find any reason, the changes in linux/include all seem
harmless and there are no changes in fs/coda.

I searched for ljmp, but it really only shows up in a few places none of
them seem relevant to Coda so I assume the linker is choking on some
code that is generated by the C compiler.

Which compiler are you using, what is the platform (i386/ia64?)?

I'll try to build 2.6.19.7 here and see if I can reproduce the problem.
