Marco,
Have you tried to build Open MPI with an external (e.g. Cygwin
provided) libevent library ?
If that works, I think that would be the preferred method.
Cheers,
Gilles
I will try.
If I remember right there was an issue in the past as
somewhere a WIN32 was defined an it was screwing the build.

Marco
I am validating a patch workaround to see if it works with both
internal and external libevent.
The build with external libevent passed all
osu-micro-benchmarks-5.4.2 MPI tests
attached patch allows build of 3.1.0 on cygwin 32 bit
and 64 bit versions, configured with
--with-libevent=external \
--disable-mca-dso \
--disable-sysv-shmem \
--enable-cxx-exceptions \
--with-threads=posix \
--without-cs-fs \
--with-mpi-param_check=always \
--enable-contrib-no-build=vt,libompitrace \
--enable-mca-no-build=paffinity,installdirs-windows,timer-windows,shmem-sysv,patcher
the 64 bit version also use
--enable-builtin-atomics
Tested with libevent 2.0.22-1
Regards
Marco
