If I change this to:

b2 --build-dir=C:/Programming/VersionControl/modular-boost/build
--reconfigure "-sNO_BZIP2=1" -d2 toolset=msvc-14.0

everything works correctly. In other words using mingw-64/gcc-6.2 
creates the error seen below but using VC++14 does not. Perhaps my 
'using zlib...' line for mingw-64/gcc-6.2 must be different but I do not 
know what it needs to be.
