Well, that would mean that the the target independent code generator
would have to cal the target code generator to ask about keywords, but
as this is sometimes context sensitive it would be bound to get it wrong
sometimes. We need to document this more clearly. The C compiler usually
gives you a strong hint as to what is going on, but other compilers may
not be so good.

This needs to go into the getting started docs basically, because
everybody reads those right? ;-)
