That looks related to something I just ran into.

I'm going through the matrix
http://www.kegel.com/crosstool/crosstool-0.28-rc37/buildlogs/0.28/
trying to fix up all the broken combinations of gcc/glibc/linux/arch
(not going to any great lengths, just getting the odd patch from
cvs, usually).  Some of these combinations aren't likely to be
too useful, but what the heck.

When cross-building linux-2.6.8 for ia64 with glibc-2.2.5, I just ran into the error

Somehow I don't get this error when building with glibc-2.3.2 or newer,
dunno why.

I'll probably give up on glibc-2.2.5 for ia64 for now
unless somebody happens to point me towards a fix.

Thanks,
Dan

include/asm-ia64/offsets.h is generated and is per kernel build
specific, which makes it pointless to store it in glibc.  Unfortunately
there are a couple of glibc header files that include asm/offsets.h,
even when not building the kernel.

The glibc headers should be corrected to skip the kernel specific code.
As a quick and dirty workaround, it might be easier to do what the
kernel does to work around the recursive dependency.  Create a dummy
include/asm/offsets.h containing just this line.
