Hi Jeff,
please apply both patches

the current 3.1.0 package is built with the first one and libevent internal.
http://www.cygwin.com/ml/cygwin-announce/2018-06/msg00010.html


While both the internal and external build complete and pass the tests,
only the internal one is correctly working with examples and
osu bechmarks.

The build with external libevent frozes with no messages when trying the
examples.
For personal reason I have no much time to investigate; so it could take 
time to identify the root cause.

One possibility is that libevent package was built with gcc-6.3 and
now for openmpi I am using the gcc-7.3.

Same for 3.1.1rc1

Regards
Marco

I will try.
If I remember right there was an issue in the past as

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
