After experimenting a bit more, I've been able to exactly re-produce what
Andrey saw. I would consider this something that would be a blocking bug
for the 1.59.0 release, as it prevents any user from successfully building
64-bit binaries of boost with least without the user going
into their temp directory and editing a file that was created by boost

Looking at the boost-build code, this batch file is created in
build/src/tools/msvc.jam:744. This file will create the temp file in
question by grabbing the output of a run of the visual studio environment
setup routine (i.e. C:\Program Files (x86)\Microsoft Visual Studio
14.0\vc\vcvarsall.bat amd64). However, for the msvc-14.0 / address-model=64
case, it seems that it is combining the 32 bit and 64 bit variables into
one causing this issue (and other variables that shouldn't be set by the
amd64 run, such as FrameworkVersion32 and FrameworkVersion64...just running
the above command only sets FrameworkVersion64).

Is it possible that build is running the 32 bit variable file, then running
the 64 bit instance?
