Dear boost users

On FreeBSD 8.1 with boost 1.43 and gcc 4.2.1 we have lots of warnings like:

...
/usr/local/include/boost/type_traits/is_unsigned.hpp: In instantiation of  
'boost::detail::is_ununsigned_helper<short int>':
/usr/local/include/boost/type_traits/is_unsigned.hpp:73:   instantiated  
 from 'boost::detail::is_unsigned_imp<short int>'
/usr/local/include/boost/type_traits/is_unsigned.hpp:123:   instantiated  
 from 'boost::is_unsigned<short int>'
/usr/local/include/boost/type_traits/make_unsigned.hpp:110:   instantiated  
 from 'boost::detail::make_unsigned_imp<short int>'
/usr/local/include/boost/type_traits/make_unsigned.hpp:130:   instantiated  
 from 'boost::make_unsigned<short int>'
/usr/local/include/boost/lexical_cast.hpp:846:   instantiated from here
/usr/local/include/boost/type_traits/is_unsigned.hpp:40: warning:  
comparison between 'enum boost::detail::is_unsigned_values<short  
int>::<anonymous>' and 'enum boost::detail::is_unsigned_values<short  
int>::<anonymous>'
...

Similar warnings about "comparison between ..." pop up in the  
serialization library as well.

What is the easiest way to suppress these warnings? I tried using the  
switches "-Wno-sign-compare" and "-Wno-conversion", but the warnings don't  
go away.

Thanks for your help
James
