------------------------------+---------------------------------------------
 I'm updating from boost 1_49 to 1_50, a project that uses pre-compiled
 headers and MSVC 2010.  I find I'm getting:

 {{{
 shared.lib(stdafx.obj) : error LNK2005: "struct
 boost::container::allocator_arg_t boost::allocator_arg"
 (?allocator_arg_at_boost@@3Uallocator_arg_t_at_container@1_at_A) already defined in
 stdafx.obj}}}
 }}}

 and consequently:

 {{{
 fatal error LNK1169: one or more multiply defined symbols found
 }}}

 I'm wondering if perhaps the declaration of allocator_arg in
 thread/detail/memory.hpp should be:

 {{{
 BOOST_STATIC_CONSTEXPR allocator_arg_t allocator_arg = {};
 }}}

 P.S.  I feel I'm really sticking my neck out commenting on your code, but
 it's the only thing that makes sense to me.
