Dear all,

I have tried to build Boost 1.59.0 on Windows with MSVC 2015 including 
zlib support for iostreams.
While this has never been a problem on Linux, I cannot get the "zlib : 
yes" message from b2, and I always get both 
libboost_iostreams-vc140-mt-1_59.lib and 
libboost_zlib-vc140-mt-1_59.lib, while I should only get the former if 
zlib had been recognized.

This is the command line that I have used:

b2 -a -q -j4 address-model=64 link=static threading=multi 
runtime-link=shared variant=release --with-iostreams 
-sZLIB_SOURCE="C:/64/boost_1_59_0_py35_build/source/zlib-1.2.8"

according to the instructions found in

http://lists.boost.org/boost-users/2014/04/81927.php

I have also tried to set the environment variable as suggested in

http://lists.boost.org/boost-users/2014/04/81894.php

but this didn't help either.

Could someone tell me what am I doing wrong?

Thanks a lot in advance for your help, kind regards
Paolo
