[boost] is_convertible warning when used with float or double types

I am getting a strange warning message when using is_convertible<> to 
test floats and doubles with GCC 3.2 (RH 8.0 release) and boost 1.30.

When I write this code:

bool test = boost::is_convertible<float,int>::value;

I get the following warning:

test.cpp:129:   instantiated from `boost::is_convertible<float, int>'
test.cpp:129:   instantiated from here
/boost/boost/type_traits/is_convertible.hpp:128: warning: passing
    `float' for argument 1 of `static yes_type
    boost::detail::checker<T>::_m_check(T, int) [with T = int]'

I could just ignore the warning, but I am seeing this with 
boost::variant (the variant contains float and double) and there are a 
LARGE number of warnings output. :(

Can anyone suggest a work around, am I using it wrong, or is this a 
known issue with type_traits?

Thanks,
Allen
