Subject: [boost] [VS++ 2015 CTP 6] [build] Workaround for Visual Studio 2015 CTP 6 Preview breaking Boost.Build

If you have previously been running Boost.Build on toolset=msvc-14.0
(Visual Studio 2015 Preview), installing CTP 6 causes some bjam/b2 builds
to fail because of missing include files.
What's happening is that Boost.Build caches several files in
C:\Users\<name>\AppData\Local\Temp. For my installation these files are:
b2_msvc_14.0_vcvarsall_x86.cmd
b2_msvc_14.0_vcvarsall_x86_amd64.cmd
b2_msvc_14.0_vcvarsall_x86_arm.cmd
but the introduction of the new universal runtime stuff in CTP 6 added some
additional paths to vcvarsall, so the cached files are no longer correct.
The workaround is to simply delete the b2_msvc_14.0_vcvarsall* temporary
files. The next time bjam/b2 is run correct versions of the files will be
regenerated.
