Boost 1.60 fails to build with VC14

[anonymous]

On a Windows 7.1 x64, from the Developer Command Prompt for VS2015 (*not* running as a privileged user):

C:\Users\user\Desktop\boost_1_60_0>cl
Microsoft (R) C/C++ Optimizing Compiler Version 19.00.23506 for x86
Copyright (C) Microsoft Corporation.  All rights reserved.

C:\Users\user\Desktop\boost_1_60_0>bootstrap
Building Boost.Build engine
The system cannot find the file C:\Users\user\Desktop\boost_1_60_0\tools\bu
ild\src\engine\bootstrap\jam0.exe.
'.\bootstrap\jam0' is not recognized as an internal or external command,
operable program or batch file.

Failed to build Boost.Build engine.
Please consult bootstrap.log for further diagnostics.

You can try to obtain a prebuilt binary from

   http://sf.net/project/showfiles.php?group_id=7586&package_id=72941

Also, you can file an issue at http://svn.boost.org
Please attach bootstrap.log in that case.

I have attached bootstrap.log as requested, but as far as I can tell it's not very helpful, I am not sure what is going on.

I have attempted the same process from the VS2013 command prompt and it was successful. I have attempted the same process from the VS2015 command prompt with Boost 1.59 and it failed with the same error.
