[Bug c++/986] g++ misses warning for & on temporary

[raf2 at msux dot cjb dot net]

I first was hit by an error using MinGW... when I compiled and executed the
first attached file, it wrote:

        John drives a: "bus"
        Otto drives a: "bus"

Which was wrong, I reported the bug and a guy from MinGW kindly explained that
if it worked then that would be purely by accident and added:
" When you declare the argument without '&' then it will make a temporary copy
of the Automobile object on the stack, but it is wrong to store a reference to
a temporary object because it will be invalid after the constructor returns.".
