Indeed, however, in this case it seems to be a compiler bug rather than 
a new feature (according to Roland). If it is a compiler bug then it 
doesn't make much sense to work around bugs in old compilers that we 
don't recommend anyway, unless it is very easy. I don't know enough C++ 
yet to do it though. Any volunteers?
