In trunk revision 65195 I've added non-intrusive (meaning, it works
for any exception object, not only the ones wrapped with
boost::enable_current_exception) exception_ptr support for MSVC 7.1
and 8.0, entirely based on an implementation Anthony Williams had
posted months ago (on other MSVC versions the intrusive support is
used as a fallback.)

Because I made some changes and I've done only limited testing, to
enable it you must #define BOOST_ENABLE_NON_INTRUSIVE_EXCEPTION_PTR.
You'll also need to link
libs/exception/src/clone_current_exception_msvc.cpp in your project.

I'm assuming MSVC 9.0 and newer will just work as soon as the
appropriate exception_info_offset value is defined in
clone_current_exception_msvc.cpp. Anthony?

Non-intrusive exception_ptr support for other compilers is now easy to
integrate in Boost Exception too. Hopefully someone can provide
suitable implementation for GCC at least (I can help with the
integration.)
