This is nice. Would you have any objections to me including it in 
the rational library, as a regression test? I'll also fix the problems it 
raised.

There were a number of issues with MSVC. One was that

    using boost::gcd;
    ... gcd<inttype>(1,2) ...

didn't work. I changed it to

    ... boost::gcd<inttype>(1,2) ...

More MSVC breakage for the list?

(Actually, *having* a list of MSVC breakage like this would be 
useful. Does anyone have one, and if so, would it be worth 
including in boost as reference material? In order to remain 
unbiased, it would probably be good to not restrict it to MSVC, but 
I expect that to be the worst culprit...)

Paul.
