The only compiler I know of that doesn't have type_info in std is Embedded VC++ 4.2; it is what prompted me to ask for the addition of BOOST_NO_STD_TYPEINFO to make shared_ptr compile. Even eVC++ 4.2 is able to eat std::exception though (if I recall).
There are a few other configurations where class "exception" may be present but in the global namespace:
STLPort when import of C std lib names is disabled. VC6. VC6 + updated dinkumware std lib.
VC6 definitely has std::exception. It's possible that STLPort on top of VC6 and with C import disabled doesn't, I can't check at the moment. Still, shared_ptr uses std::exception directly, it doesn't look at the macros, and nobody has reported it not to work. (It didn't work on eVC 4 for other reasons, but not for this one.)
