While compiling the brickos kernel under gcc-3.2 and binutils-2.12.0 I was
getting errors about nb_tasks and nb_system_tasks not being te same as
their declarations so I made them volatile just like in the header and the
kernel now compiles. The demos except trailerbot and c++.cpp compile and
function ok. I'll work on those demos later. Here is the tiny patch which
should work against CVS and the test tarball brickos-0.2.6.07.nmChg;

I don't know if this breaks anything or if this is even the right thing to
do.
