Comment (by rwebb <richard.webb@…>):

 I suggested the above change because what appeared to be causing the
 failure was that the absence of BOOST_SERIALIZATION_SOURCE in
 shared_ptr_helper.cpp and basic_serializer_map.cpp was resulting in
 BOOST_SERIALIZATION_DECL being set to __declspec(dllimport) when it needs
 to be __declspec(dllexport) for the dll build to work.

 There seems to be something else going on here as well though, as if i run
 the regression tests, i get loads of warnings along the lines of :

 {{{
 gcc.link
 ..\..\..\bin.v2\libs\serialization\test\test_derived_text_archive.test
 \gcc-mingw-4.5.0\debug\test_derived_text_archive.exe
 Info: resolving vtable for boost::archive::archive_exception by linking to
 __imp___ZTVN5boost7archive17archive_exceptionE (auto-
 importc:/mingw450/bin/../lib/gcc/mingw32/4.5.0/../../../../mingw32/bin/ld.exe:
 warning: auto-importing has been activated without --enable-auto-import
 specified on the command line.
 This should work unless it involves constant data structures referencing
 symbols from auto-imported DLLs.)
 }}}

 It doesn't seem to cause any problems with the tests, but i don't know how
 auto import works so i can't say anything more about it.
