I think we'd be interested in looking at possibly adding this to the code base. We still need to announce this (and will shortly), but our Windows maintainer has moved on to other pastures. So support for native Windows operations is ending with the 1.6 series, barring someone stepping up to fill the void.

Having a cygwin alternative would let people at least continue to work on the Windows platform, albeit in a different mode. Is this something you are interested in pursuing?

I built and packaged openmpi-1.6.3 for cygwin.
Before deploying it as an official package, I would
like feedback from testers.

Source and binary here:

To install using cygwin setup program
setup.exe -X -O -s http://matzeri.altervista.org

Current configuration is:

         LDFLAGS="-Wl,--export-all-symbols -no-undefined"  \
                 --disable-mca-dso \
                --without-udapl \
                --enable-cxx-exceptions \
                --with-threads=posix \
                --without-cs-fs \
                --enable-heterogeneous \
                --with-mpi-param_check=always \
                --enable-contrib-no-build=vt,libompitrace \
                --enable-mca-nobuild= memory_mallopt, paffinity, installdirs-windows, timer-windows, shmem-sysv

Only additional patch

C, C++ and Fortran pass basic tests

$ time mpirun -n 4 ./hello_f90.exe
 Hello, world, I am            0  of            4
 Hello, world, I am            2  of            4
 Hello, world, I am            1  of            4
 Hello, world, I am            3  of            4

real    1m9.607s
user    0m1.542s
sys     0m2.135s

But I guess there is a long delay/timeout on startup.
