  That makes a bit more sense.  Somehow
everything from clang-win is getting dropped.

Unless you reformatted this it looks wrong.  There should be a
new line before the last '

notice: [clang-cfg] condition:
'<toolset>clang-win-3.7-vc14/<architecture>/<address-model>', setup:
'call "C:\Program Files (x86)\Microsoft Visual Studio
14.0\VC\vcvarsall.bat" x86 > nul
    '

  I pasted this into my user-config.jam, and commented out
everything else, and I still can't reproduce the problem.

$ b2 -v
Boost.Jam  Version 2015.07. OS=NT.

I tried develop:

    Remove wrong if.  This case is already handled correctly by the next
else if

and master:

    Merge remote-tracking branch 'origin/develop'

The only local change to Boost.Build is
the patch that I sent.

I just installed clang with microsoft codegen,
and now I'm getting your original error:

"clang.exe: error: no such file or directory: '/Od'"

  I suspect that the problems that you're getting
are caused by something other than my patch.
If you revert it, do you go back to the original
problem?  My only guess at this point is that
you're initializing multiple versions of clang,
and they're interfering with each other.
