[boost] [rational][operators] VC6/7 supported? (Trying to clear regressions)

What's the state of support for VC6/7 in Boost.Operators?

I'm asking because I started investigating the remaining regressions for 
Boost.Rational and I've come up against a road-block: I can get everything 
to work (at least I think so), but not the comparison operators, so:

my_rational_1 != my_rational_2

doesn't compile with VC6/7, but does with everything else.  I'm assuming 
that's because these compilers don't find the necessary friend-functions in 
the operators base classes, or is there something else going on here?

The error message is:

rational_test.cpp(261) : error C2678: binary '!=' : no operator defined 
which takes a left-hand operand of type 'class boost::rational<short>' (or 
there is no acceptable conversion)
        ../../boost/test/test_case_template.hpp(73) : while compiling 
class-template member function 'void __thiscall 
basic_rational_suite::rational_comparison_test<short>::test_method(void)'

BTW is the use of Boost.Operators by the rational lib new to this version?

If so we might just have to mark up VC6/7 as unsupported.

Thanks,

John.
