OCaml cross-compiler.

[Romain Beauxis <toots@rastageeks.org>]

	Hi all !

I have done more work on the ocaml cross-compiler for windows.

I have succesfully compiled a fairly large application which runs on windows.

Hence, I believe the package may be tested now if you are interested.

The package can be found in the mingw32-ocaml git repository [1] and compiles 
under cowbuilder on amd64.

For the details, I have finally choosed to locate the standard files in 
/usr/i586-mingw32msvc/lib/ocaml, which seems consistent with the location of 
the files shipped by mingw32.

The package now also includes a support for ocamlfind. In order to use it, you 
should set the environment variable OCAMLFIND_CONF to /etc/i586-mingw32msvc-
ocamlfind.conf

In order to also force the build system to choose the ocaml cross-compiler, 
you may add /usr/i586-mingw32msvc/bin at the beginning of the PATH variable:

  export PATH=/usr/i586-mingw32msvc/bin:$PATH

Eventually, when the build system uses the autoconf tool, you can build the C 
libraries with the following options:
  ./configure --prefix=/usr/i586-mingw32msvc --host=i586-mingw32msvc

It is convenient to install those libs directly in /usr/i586-mingw32msvc, 
though not very clean. However, it seems that /usr/i586-mingw32msvc/local is 
not recognized by the mingw32 cross-compiler.

Please, let me know if you have any feedback from this..
