So based on the config macros below, 4.1.3 shouldn't have had
the definition of the exception copy assignment operator in it
(i.e., it should have come from the runtime library), whereas
4.2.0 should have it in it. Yet the 4.1.3 examples aren't
finding the symbol either in the MSVC runtime (which is the
same), or in the 4.2.0 dll?
You are running the 4.1.3 examples with the 4.2.0 library,
right? I.e., not 4.2.0 examples with the 4.1.3 library. Just
checking.
I guess you are given that Farid is seeing the same unsats.
Could 4.1.3 be linking with some additional/different runtime
(archive) libraries than 4.2.0? That still doesn't explain why
the symbols aren't found in 4.2.0 if they're defined there
(according to the config macros).

#define _RWSTD_NO_BAD_CAST_ASSIGNMENT
#define _RWSTD_NO_BAD_CAST_COPY_CTOR
#define _RWSTD_NO_BAD_CAST_DEFAULT_CTOR

This is pretty consistent with what I'm expecting. I'm looking into the
config tests now to see why we have a change in behavior with the same
configuration.
