[boost] [Serialization] BOOST_CLASS_EXPORT regression on SunCC

>From version 1.34 to 1.35, the export of classes was modified so that
all the archives did not need to be included before calls to
BOOST_CLASS_EXPORT. I don't know why this was a problem to begin with.

Anyway, this feature used to work on SunCC but with the new changes,
there is a regression. This is caused by the dependence on ADL to
instantiate the ptr_serialization_support members: SunCC just doesn't do
it. So the instantiations never occur and you get an assertion failure
when running the serialization tests under debug:

Assertion failed: it != boost::serialization::singleton<
oserializer_map<Archive> >::get_const_instance().end(), file
vendor/boost_1_37_0/boost/archive/impl/archive_pointer_oseri\
alizer.ipp, line 64

I know how to fix it (instantiating manually for each
Archive,Serializable pair, not a huge problem).

I would suggest that Boost Serialization should have a fallback
                                                        mechanism for
these compilers. Perhaps along the lines of the old export
functionality where the user would define the archives they are
interested in.

Thoughts?
