      So you're building for 32 bit mingw

...and that's logical result.  Along the same lines you could try to
link powerpc-linux ncurses against arm-freebsd binary.  That just won't
work.

What you need is a i686-mingw ncurses.  Have a look around on the net or
try to build your own.  However, it will probably not work correctly in
a Cygwin pseudo tty due to lack of the Cygwin compat layer implementing
them.

Nope, use cross compilers.
