Clang and Boost under Windows

Currently there is no toolset in Boost Build for running clang in Boost under Windows. Is this possible ? Should clang, built with MingW, or more improbably VC++ 10, be able to compile Boost libraries under Windows ?

It would be a boon to allow Windows programmers to test Boost libaries again clang under Windows. Currently I have been using gcc and msvc++. Comeau has too many problems getting it to work properly. I would love to be able to test with clang also.
