[Boost-users] object with external linkage in boost/tuple/detail/tuple_basic.hpp

When I

#include<boost/tuple/tuple.hpp>

in multiple files and compile them with the Digital Mars compiler, its 
linker complains about multiple definitions of an object called ignore. 
The problem is in the file
boost/tuple/detail/tuple_basic.hpp, which has this line:

detail::swallow_assign const ignore = detail::swallow_assign();

This works when I compile with gcc or the Microsoft compiler, but it 
shouldn't be there, should it? I thought the only things with external 
linkage that should go in headers are special cases like inline 
functions. If I'm wrong and this is a bug in the Digital Mars compiler 
or linker let me know and I will go report it.

Thanks,
Mike Benfield
