Eric, your assumption hits the spot.
When I was running a quick test of Clang with Boost under Windows,
I built Clang without problems.
Next, I tried to compile Boost and I had got the errors as reported in
ticket #5943.
So, I assumed it is Boost.Build issue and abandoned any further testing.
At that time, I hadn't monitored Clang development closely, so I had no idea
about the now well-known problems with ABI (RTTI, streams)
between Clang and Visual C++ C/C++ Run-Time libraries.

Later, I have seen some random notes about possible use of Apache STDCXX
or even LLVM/libc++ with Clang on Windows, though nothing officially confirmed,
so I decided to wait a bit.
Also, I may be thoroughly wrong, but according to what I have seen on
libc++ mailing list
it seems to be targeting Windows through MinGW, MinGW is not my cup of tea,
so not even tried it.

It feels to me we have number of C++ std libraries being developed, but none
included Clang on Windows support in near roadmap.
