[boost] Math/Quaternions compile problem in VC++6

My Visual Studio 6 requires the trigonometry functions sin, cos, etc. to
be prefixed with :: in the quaternion.hpp, otherwise I get:

" 
...\boost-1_32\boost\math\quaternion.hpp(1686) : error C2784: 'class
boost::math::quaternion<T> __cdecl boost::math::sin(const class
boost::math::quaternion<T> &)' : could not deduce template argument for
'const class boost::math::quaternion<T> &' from 'const double'

...\main.cpp(112) : see reference to function template instantiation
'class boost::math::quaternion<double> __cdecl
boost::math::spherical(const double &,const double &,const double
&,const double &)' being compiled
" 

I'm using a quaternion<double> here.
 
Changing the line
 
    T    d = sin(phi2);
 
into
 
    T    d = ::sin(phi2);
 
fixes the problem (for that line).
 
The rest of the file contains lots more trigonometry (and other math)
functions, which probably also need to be prefixed.
