NetBSD (any platform).  Can be reproduced on Solaris, SunOS, and OSF/1
(that's all the stuff I have access to).

Um, hello?  Why do the exception frames _exist_?  I'd _love_ to see the size
information for the ones you omitted.

You're reproducing the problem, just that your linker can partially cope by
the use of weak symbols.  However, not all linkers can remove common code
this way - and this code SHOULD NOT BE GENERATED IF IT IS NOT USED.  In
other words, the only thing the source file

#include <stdexcept>

should generate is the symbol "gcc2_compiled".  That's all.
