I guess MSVC doesn't like the 'internal' struct that got introduced in
2.0.15.  If the comment in type_traits.h is correct, MSVC doesn't need it.
Modifying MSVC_Net2003\sigc++config.h and copying the

   #define SIGC_SELF_REFERENCE_IN_MEMBER_INITIALIZATION 1

line into the SIGC_MSC section should fix the build problem.
