Sorry, I meant split it into different statements.  Along the lines of:

struct generic_block *b = (struct generic_block*)func;
void (*fn)(void*,...) = b->invoke;
fn.fn_ptr.cxa_func = (void (*)(void*))fn;

Well, I wouldn't object to that, but it would be good to fix this - we still want to be able to build the base system with gcc (or another compiler), even if we don't encourage it...
