+CROSS COMPILING FROM LINUX TO WIN32:
+
+It is also possible to cross compile from Linux to windows using the MinGW
+cross tools and even to run the test suite under Wine, the Linux/*nix
+windows emulator.
+
+On Debian and Ubuntu systems, these cross compiler tools can be installed
+by doing:
+
+    sudo apt-get mingw32 mingw32-binutils mingw32-runtime wine
+
+Once these tools are installed its possible to compile and test by
+executing the following commands:
+
+    ./configure --host=i586-mingw32msvc --target=i586-mingw32msvc \
+         --build=i586-linux
+    make
+    make check
+
+The above has been tested with the following versions of the tools on
+Ubuntu's Hardy Heron release:

+    mingw32             4.2.1.dfsg-1ubuntu1
