I do not know how/why travis was enabled.
That being said, the errors look legit to me, and there are two
1) with clang 5.0

^~~~
:33:1: note: expanded from here
(there are many kind of errors like this one, could be a clang 5 issue
or something we failed to detect with this compiler)
2) with "make distcheck"
Here is how to reproduce the issue
export CPPFLAGS=-I$HOME/bogus/include
./configure --prefix=$HOME/bogus
make
make distcheck
the first configure reports
== Modular Component Architecture (MCA) setup
checking for subdir args... '--prefix=/home/gilles/bogus'
'CPPFLAGS=-I/home/gilles/bogus/include'
but the second one (invoked indirectly by make distcheck) reports
== Modular Component Architecture (MCA) setup
checking for subdir args...
'--prefix=/home/gilles/src/ompi-master/openmpi-gitclone/_inst'
'CPPFLAGS=-I. -I./orte/include
-I/home/gilles/src/ompi-master/opal/mca/event/libevent2022/libevent
-I/home/gilles/src/ompi-master/opal/mca/event/libevent2022/libevent/include
-I/home/gilles/src/ompi-master/opal/mca/hwloc/hwloc201/hwloc/include
-I/home/gilles/bogus/include -I/usr/local/include -I/usr/local/include'
and we endup using the include files from the embedded hwloc of the
first 'make' and linking with the system hwloc, which fails (no mangling
and possibly version inconsistency)
I will run a bisect to search when this started.
Cheers,
Gilles

Did someone enable Travis CI on GitHub:open-mpi/ompi?
I thought we had specifically disabled Travis after we kept running into
problems with it...?
I ask because it's failing on some PRs for reasons that seem to have nothing to
do with the PR. I don't know if our Travis setup has bit rotted, if there's a
genuine problem, or if Travis is just acting wonky...
