Thanks to the great work from Richard Jones on building a OCaml cross-compiler for windows, we now have a similar package in Debian !
The package is called mingw32-ocaml and has just been accepted yesterday.
We have already used it to build a win32 version of liquidsoap.
I hope that this cross-compiler will be useful to OCaml developers, in particular in porting their application to the world of windows and fences, in order to spread the word about how great OCaml is :-)
