Ok, this means zlib is detected, which is good. The library you mention
previously, libboost_zlib-vc80-mt-gdp-1_39.lib, is not actually supposed
to be produced, but Boost.Iostreams autolinking code wants it.

Can you try adding BOOST_ZLIB_BINARY=xxx macro when building your project,
where xxx is the basename of the zlib library?
