I agree with you, in the sense that: let's not work hard to support
exception handling behavior of pre-standard C++ compilers.

OTOH, pre-standard C++ compilers are definitely a concern for testing.
I usually do pre-release testing on a couple of systems that have fairly
old and non-standard C++ compilers (no namespaces etc).  I don't want to
see errors stemming from this.

Thanks,
Ralf
