Hello Robert,
Thanks for the response. 
The warning is also seen with the latest 1.43 version of the Boost library also. I tried compiling with the g++ 3.4.6 and noticed the same warning. Is there a particular complier option required to disable this warning (or perhaps resolve)?
 
Thanks
Sulakshan

One work around would be to upgrade you compiler to a more recent version.
The oldest version we have in out test matrix is gcc 3.4.6 and it's not
emitting any warnings.  Also you might want to mention which version
of boost you're using.
