further issue on cygwin, in addition to an easy libevent issue that I already patched.

Is that a patch we should:

a) submit upstream to libevent
b) patch locally in Open MPI

?

Hi Jeff,
ideally (a) as it seems that any new libevent version is causing (b).
I looked at the old patch submitted for 1.7.3 for guidance.

As soon I finish the test I will submit the new patch.


Looking in more depth, we have already libevent as
cygwin package

$ cygcheck -cd |grep event
libevent-devel                          2.0.22-1
libevent2.0_5                           2.0.22-1

and I see that it builds from source with no patch,
so I see two possibilities:

or there is a version mismatch as from
  libevent2022/libevent/configure.ac
it seems a patched 2.0.21-stable and not a 2.0.22
release;

or something is defining WIN32 before configuring
libevent and creating the problem with Cygwin
that requires a lot of
   #if defined(WIN32) && !defined(__CYGWIN__)

Marco
