What can be done to get the Linux 2.6.39.4 kernel patched with Reiser4 to build ?. The i586 build fails and the x86_64 build passes.

[<doiggl@velocitynet.com.au>]

Hello,
I am finding problems in trying to compile a linux 2.6.39.4 kernel patched
with Reiser4-for-2.6.39.patch.gz
The i586 build failed[2], whereas the x86_64 build passes.[3]
What do I need to adjust so i586 builds properly.
Has anyone else successfully built the with the i586 architecture ?
Is so, what does your .config list ?
My .config listing starts at line 3341 in [2]
Thanks Glenn.
