[Mpi3-rma] Ticket for WG discussion

concerning Ticket 349.
(*) In Fortran, the displacement for dynamic windows may be signed
      since MPI_BOTTOM of Fortran is not (void *) NULL..
(*) Fortran doesn't have unsigned integers, thus you cannot use
      a Fortran version of MPI_Disp for arithmetics (such as disp++).
(*) MPI Displacements in general may be signed.
      They might be relative to any address.

Therefore, I can't see that the Proposed Solution 2 solves the problem.

Subject: [Mpi3-rma] Ticket for WG discussion

Hi All,

I would like to propose the following two tickets for discussion in
today's WG meeting:


#349 is a bugfix that definitely needs to be addressed.  #344 is an
"elegance of the interface" ticket where I would like to poll the WG to
determine the level of support and determine if this should be pursued.

I unfortunately need to duck out at 4pm today, so if possible, I propose
that we discuss these at the beginning of the meeting.
