It's correct if they're being linked to separate DLL files.  Looking at 
the jamfile, that doesn't appear to be the case; and it's not correct if 
they end up in the same binary.

binary_iarchive.cpp does define BOOST_ARCHIVE_SOURCE; perhaps these were 
originally intended to live in separate compiled libraries?
