[ITP] OpenCoarrays 1.0

[Alessandro Fanfarillo]

Dear all,

I would like to port the OpenCoarrays library (opencoarrays.org) on
Cygwin. The library implements the multi-image Coarray Fortran support
on GCC 5.1 and it is distributed under BSD 3 license.
It requires GCC 5.1 and a MPI implementation (OpenMPI works fine).
Since this is the first time I work on a Cygwin package, any
suggestion/instruction/comment is more than welcome.

Regards

Alessandro
