build OPAM for mingw

[dweil]

I tried to build OPAM for mingw from cygwin (with the cross compiler) :

export CC=i686-w64-mingw32-gcc
./configure
make

and got

make -C ocp-build
make[1]: Entering directory `/cygdrive/d/home/ocaml_src/opam/ocp-build'
awk '{ print "external "$1": unit -> unit = \"" $1 "\"" }' primitives > primitives.ml
ocamlc -o ocp-build.run -custom -make-runtime win32_c.c primitives.ml unix.cma  -cclib -lunix
** Fatal error: Error while reading D:/cygwin/usr/i686-w64-mingw32/sys-root/mingw/lib/libmoldname.a: End_of_file
File "primitives.ml", line 1:

Will OPAM be supported for mingw ?

Closing as duplicate of #246. The windows support is an ongoing work, it won't be ready for the 1.1 release.
