I have prepared a llvm-clang compiler targeting 32bit Windows. I used 3.7.1 and applied this patch. I get to something that almost works, apart that I have errors with boost.
If I compile my project (that normally works with mingw-gcc) using my usual boost 1.53 headers I have troubles including boost/interprocess components

If I then try to recompile boost with:
bootstrap.bat mingw
b2 toolset=clang --with-thread --with-filesystem --with-signals --with-test --with-system --with-regex --with-program_options --with-serialization variant=release link=shared threading=multi
Depending on the various version of boost I get a lot of warnings that I could try to ignore, but also some errors:
For 1.56 and 1.57 just these: (is not much, but I don't know how to get rid of it)

For 1.59 and 1.60 a bunch of MMX related error, which is, as far as I can see, not a feature that I can control when preparing my llvm-clang:

Is there a way to get any version of boost to work with clang 32bit under Windows in a MinGW set up?
I have also tried llvm 3.8.0, but I cannot prepare it because my MinGW toolchain doesn't support some part of C++11 (and so other versions that I have tried, see here).
