I guess I haven't explained things very well: you are right that scoped
guards will work in any situation, and to be honest I happen to think they
are easier to maintain as well.  However, the point I was trying to make was
that if the compiler doesn't support C++ exceptions, then neither structured
C exceptions nor POSIX signals will ever unwind C++ objects on the stack.
