[ECOS] Context.s problem

I don't know if this information helps anybody. But I think this problem has
something to do with assembly and the compiler. Because when I work around the
problem raised with context.s I get another error on variant.s. I can work
around this problem as well but that is not the answer for my problem. I need to
get the source of the problem!
Does anybody have an idea??

The pre-built toolchain eCosCentric provide is 3.2.1. That is known to
work.
