1857	IA64, GCC 4.3, redefinition of 'struct boost::serialization::implementation_level<std::vector<long int, std::allocator<long int> > >'	Stefan Eckardt	Robert Ramey	"Hi,

I get the following error message compiling with gcc 4.3.0 on ia64:
{{{
/usr/local/include/boost/serialization/vector.hpp:185: error: redefinition of 'struct boost::serialization::implementation_level<std::vector<long int, std::allocator<long int> > >'
/usr/local/include/boost/serialization/vector.hpp:185: error: previous definition of 'struct boost::serialization::implementation_level<std::vector<long int, std::allocator<long int> > >'
/usr/local/include/boost/serialization/vector.hpp:185: error: redefinition of 'struct boost::serialization::implementation_level<std::vector<long unsigned int, std::allocator<long unsigned int> > >'
/usr/local/include/boost/serialization/vector.hpp:185: error: previous definition of 'struct boost::serialization::implementation_level<std::vector<long unsigned int, std::allocator<long unsigned int> > >'
}}}
This error can be reproduced with this small example
{{{
#include <boost/serialization/vector.hpp>
int main()
{
	return 0;
}
}}}
Removing the lines
{{{
    BOOST_SERIALIZATION_COLLECTION_TRAITS_HELPER(signed long, C)     \
    BOOST_SERIALIZATION_COLLECTION_TRAITS_HELPER(unsigned long, C)   \
}}}
from boost/serialization/collection_traits.hpp solves this problem for me. 

Thanks for considering this issue.
