Your kernel sources and all the mentioned tools are now OK, and probably
were OK already. The only thing that is giving you the error is the
version of the gcc compiler that you use (2.96).

It is the *compiler* (gcc-2.96) that has a bug here. As this version of
gcc has many other bugs developers no longer work around difficulties
this specific version of gcc has.

What you can do is upgrade your gcc package to a later version (3.2.x or
3.3.x or even later from your distribution). As a workaround I've made a
little patch that you can apply to fs/proc/array.c if you still want to
keep using gcc 2.96 for a little while. It's archived here:
