www.mingw.org?

zlib.h is part of cygwin.  Of course it can't be found if you say
-mno-cygwin.  It seems like many people assume that -mno-cygwin is some
magical way to get all of cygwin's functionality without the use of the
cygwin dll.  It isn't.  The libraries in /usr/lib and the include files
in /usr/include are cygwin files.  The files in /usr/lib/mingw and
/usr/include/mingw are provided for base mingw support.  If you need
more or have more detailed mingw questions, then the mingw mailing list
is the place to go.
