VC7.1 operator << doesn't work for non-const objects

[s-sivkov]

The manual says operators & and << are equals. In fact,
operator << doesn't work for non-const objects, but
operator & works.
Yere is simple example:
if i change string
const gps_position g(35, 59, 24.567f);
to
gps_position g(35, 59, 24.567f);
(function main() in demo.cpp)
then i will see compilation error:
---
c:\Boost\include\boost-1_33\boost\archive\detail\oserializer.hpp(566):
error C2027: use of undefined type
'boost::STATIC_ASSERTION_FAILURE<x>'
        with
        [
            x=false
        ]
---
but for operator & (i.e. from
    oa << g;
to
    oa & g;
)
all works perfectly.

This is intentional - read the manual regarding tracking and 
the rationale section which describes this behavior
