Re: [boost] [serialization] BOOST_CLASS_EXPORT

Method I

Make your function "inline" either explicitly or by including
the definition in the member function declaration.

This is not my favorite method.

leave the declarations in the header - but move the definitions
to a *.cpp file.  Use explicit instantiation to generate code
for all the archives you plan to use or for polymorphic archive.

This is my preferred method.
