Mostly just on Windows, though Linux has its own quirks that come up
when you use dlopen().

Well, yes and no.  Given the current structure of Boost.Serialization,
it's definitely a problem that only the library integrator can solve,
by structuring his application appropriately. However, if you were
willing to change the structure of Boost.Serialization, you could have
all those DLLs link to a common DLL which is where the singletons are
"registered" (you could create them there for a reduction in overall
code size, but I assume you want to keep that DLL as lightweight as
possible).  You'd have to explicitly *not* deliver that common DLL as
a static library.
