gcc 3.3 implements such a warning, but it may give many false positives.

Any chance we can get this flag backported so that it appears in gcc 3.2.2?

False positives are a whole lot better than code that quietly does the an
unexpected thing.

Well, are you sure OO is really affected? strict-aliasing is the default
since gcc-2.96 which means that everything since redhat-7.0 would be
affected on x86 for example. Also GCC has been very late to make this the
default at all, I think that Sun and MS compilers do this for years
already. I would be very surprised if a multiplatform project like OO still
contained reasonable amounts of aliasing-unsafe code.
