Build them in the order in which they are listed in the table.

$ make -f win32/Makefile.gcc INCLUDE_PATH=/mingw/include LIBRARY_PATH=/mingw/lib all install
$ mv /mingw/lib/libzdll.a /mingw/lib/libz.dll.a

To build the other three, run the following commands after extracting the source code:

$ ./configure --prefix=/mingw
$ make LDFLAGS=-no-undefined all install
