Notice, i was able to cross compile hello-gtk.c on debian/sid with the
following practice :

  1) install the mingw32 package.

  2) unzip all the packages from the gtkwin32 web page, including
     libiconv for which you need to move the .dll to lib and the .h to
     include.
  3) set the PKG_CONFIG_PATH variable :

     export PKG_CONFIG_PATH=/home/luther/download/gtkwin32/lib/pkgconfig

  4) launch the build :

     i586-mingw32msvc-gcc -mno-cygwin -mms-bitfields -o lib/hello-gtk
     `pkg-config --define-variable=prefix=/home/luther/download/gtkwin32
     --cflags gtk+-2.0` hello-gtk.c `pkg-config
     --define-variable=prefix=/home/luther/download/gtkwin32 --libs
     gtk+-2.0`

     notice that i moved the executable in the lib directory, so it would
     find the .dll files.

  5) launched the resulting executable under wine :

     cd lib; wine ./hello-gtk

It runs fine, but there is garbage in the widget, i will need to test it
under windows to see if it is wine related or caused by the cross
compiling.

You can then create an executable tarball :

  6) mkdir zipball; cd lib; cp -xav `find . -name \*.dll` ../zipball 

And zip the resulting directory :

  7) cd zipball; zip ../hello-gtk.zip *

Now, provided it works fine under windows, we only need a cross-ocamlc
compiler.

Friendly,
