7074	[thread] Multiply defined symbol boost::allocator_arg	anonymous	viboes	"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@boost@@3Uallocator_arg_t@container@1@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."	Bugs	closed	Boost 1.51.0	thread	Boost 1.50.0	Problem	fixed
