uml build problem 2.6.15.6/2.6.16rc6

[David Lang <dlang@digitalinsight.com>]

I'm attempting to build a UML kernel on both versions (same starting 
config before make ARCH-um oldconfig) and I get the following error on 
2.6.16rc6 (similar errors on 2.6.15.6)

this is on a dual Opteron system with a debian 3.1 64bit build

There are two ways of constructing a software design. One way is to make it so simple that there are obviously no deficiencies. And the other way is to make it so complicated that there are no obvious deficiencies.
