I'm lucky enough to not need to support 1.32 archives. I was aware of the 
shared_ptr_132.hpp issue from following the devel list.

Ok, I missed that there was no longer a need for 
BOOST_SHARED_POINTER_EXPORT_GUID in reading the changes section. Also I 
never #included boost/serialization/shared_ptr_132.hpp so I'm surprised that 
I didn't get a compiler error that BOOST_SHARED_POINTER_EXPORT_GUID was not 
defined. Most likely a VC7.1 oddity/bug.

I changed to BOOST_SHARED_POINTER_EXPORT_GUID(along with a clean build) and 
lo-and-behold all works like a charm! In fact I've been able to clean up a 
lot of kluges required to work around VC7.1 ICE's. I previously had to 
separate more than 3 exports macro calls into multiple files. Compilation is 
also much faster.

A very, very nice improvement in serialization, iostreams and all the rest 
of Boost!

Congratulations and Thanks to all involved!
