64bit build fails

Looks like the ocaml-windows64.4.04.0/opam file specifies patches which don't exist:

$ TOOLPREF64=~/mxe64dynamic/usr/bin/x86_64-w64-mingw32.shared- opam install ocaml-windows
The following actions will be performed:
  ∗  install conf-gcc-windows64 1             [required by ocaml-windows64]

  ∗  install ocaml-windows      4.04.0
