the Canadian Cross building is usually used to build the tool chain for Cygwin 
or Mingw on a Linux host.  This is much faster than building natively.  I guess 
using a Cygwin build system for a Canadian Cross build is somewhat special.

The x86_64-w64-mingw32-g++ must find <zlib.h>.  I guess zlib is missing in your 
x86_64-w64-mingw32 installation.
