[boost] Compiling with Clang 3.7.0 from windows

Subject: [boost] Compiling with Clang 3.7.0 from windows

I've downloaded the shiny new Clang 3.7 and added this to my user-config. # 64-bit version
 using clang # from http://llvm.org/releases/download.html
    : # version
      3.7.0
    : # Clang compiler .exe location
    #"C:/LLVM/bin/clang++.exe" # OK
    #"C:\\Program Files (x86)\\LLVM\\bin\\clang++.exe" # OK
    "C:\\Program Files\\LLVM\\bin\\clang++.exe" #
    : # options
  ;

If I compile a simple hello world (no Boost library calls) program using the defaults (jam  (using
up-to-date Boost develop branch)

it fails at the link complaining

c:\mingw\bin\ld.exe: unrecognised emulation mode: i386pep
Supported emulations: i386pe

which seems an odd message???

I:\modular-boost\libs\quickdox\example>b2 toolset=clang-3.7.0

If I specify address-model=32, then it runs OK - but still says "64-bit     : yes (cached)"
which isn't what I would expect?

I:\modular-boost\libs\quickdox\example>b2 -a toolset=clang-3.7.0 address-model=32

Performing configuration checks

    - 32-bit                   : no  (cached)
    - 64-bit                   : yes (cached) <<<<<<<<<<<<<<<<<<<  ???????????????????

<snip>

[Also example>b2 -a toolset=clang-3.7.0 address-model=64

fails to link as with no address-model specified (so default is 64 bit?)].

Suggestions?  

(Have I got the wrong version of mingw?  I have others from ming64 - how do I specify to use those?)

Thanks

Paul
