This Error occurs (MSVC 2003 + SP1) when calling boost::math::log1p

-------------------
c:\boost_1_34_0_beta\boost_1_34_0\boost\math\special_functions\log1p.hpp(83)
: error C2784: 'boost::rational<IntType> boost::abs(const
boost::rational<IntType> &)' : could not deduce template argument for 'const
boost::rational<IntType> &' from
'boost::math::tools::promote_args<T1,T2,T3,T4,T5,T6>::type'
        with
        [
            T1=double,
            T2=float,
            T3=float,
            T4=float,
            T5=float,
            T6=float
        ]
-------------------

Same error is thrown when trying to call boost::math::complex functions.

Any fix to this?

Most strange, VC8 handles it fine, and it appears to be a comiler bug, but I

can't find a workaround at present, so the diff below is the only fix I have

for now.
