[boost] [spirit] Deprecation warnings, can they be turned off?

In doing a top-level build of Boost (trunk) I'm seeing many messages 
like this one:

./boost/spirit/core/composite/actions.hpp:15:4: warning: #warning "This 
header is deprecated. Please use: boost/spirit/include/classic_actions.hpp"
In file included from libs/serialization/src/basic_xml_grammar.ipp:22,
                  from libs/serialization/src/xml_wgrammar.cpp:243:

Two questions:

* Is this something to worry about that the Serialization lib, and 
perhaps others, are using the deprecated headers?

* Assuming Serialization, other libraries, and users want to use the old 
headers. Is there a way for them to turn off the warning? I don't see 
anything obvious from looking at the headers themselves.

In a world where compiling Boost produces many warnings already in some 
platforms. It seems bad if we are adding even more onto the fray.
