Greetings,
For whatever reason, glibc sets sysincludes to point to the running
kernel's include directory ala...
sysincludes = -I /lib/modules/2.6.18-rc6-mm1-smp/build/include
in it's config.make instead of using installed headers, and this leads
to the compile failure below.
I just edited config.make to point to different headers, dunno if it
_should_ work as before (2.6.18-rc6 does) or not.

That's wrong. When you run 'make headers_install', the result is placed
in /lib/modules/`uname -r`/abi/include/
It looks like glibc is pointed at the raw kernel headers in the build
tree.

Don't care. <linux/err.h> is not a header which is exported to userspace
by 'make headers_install'. No userspace build, including glibc, should
ever be able to see it.

I kinda figured that was going to be the answer, but not knowing why
glibc was doing that, I thought it was worth a mention. Thanks.
