Hello,

my goal is fast portable serialization when 95% of data is in large 
binary objects.

1)
binary_archive is fast, but nonportable.

2)
text_archive is portable, but ~50x slower.

3)
portable_binary_archive looks like solution, but I'm not able to use it 
to serialize by pointer. Problem can be demonstrated in 
demo_portable_archive.cpp of boost 1.42 by changing "char c;" to "A* c;" 
and "c(std::rand())" to "c(0)".
Errors from VS2008 linker look like
error LNK2019: unresolved external symbol "public: static class 
boost::archive::detail::basic_serializer const * __cdecl 
boost::archive::detail::archive_serializer_map<class 
portable_binary_iarchive>::find(class 
boost::serialization::extended_type_info const &)" 
(?find@?$archive_serializer_map_at_Vportable_binary_iarchive@@@detail_at_archive@boost@@SAPBVbasic_serializer_at_234@ABVextended_type_info_at_serialization@4@@Z)

demo_portable_archive.obj
Any idea how to fix it?

4)
Is it possible to override text_archive to process binary objects 
faster, without converting them to text?
