[boost] [1.35] Serialization shared_ptr_132 headers cause compilation error with g++ 4.1.0

Hi,

I'm trying to update a code base to use boost 1.35 from boost 1.32. From what
I've gathered, 1.35's code is frozen and considered to be fairly stable, so I
figured that I wouldn't run into any errors caused by boost, just general
changes that occurred between 1.32 and 1.35.

Instead, it looks like I've definitely run into a bug being caused by 1.35, in
particular, the serialization headers for shared_ptr. 

The following code:

#include <boost/serialization/shared_ptr_132.hpp>
#include <boost/serialization/shared_ptr.hpp>

int main()
{
    return 0;
}

Causes the following errors:

g++ what.cc -o what -I /usr/local/include/boost-1_35/
-lboost_serialization-gcc41-mt-1_35
/usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp: In function

/usr/local/include/boost-1_35/boost/serialization/shared_ptr.hpp:124: error:
expected primary-expression before ‘>’ token

Looking at the documentation included with 1.35 says to retain
backwards-compatibility for 1.32's shared_ptr by including both headers in the
order I have included them, so I'm at a complete loss.

I must retain compatibility with shared_ptr from 1.32 since there is a lot of
serialized data floating around from 1.32, and its not feasible to find all of
it and convert it mechanically.

I hope someone can lend a helping hand.

Thanks,
