13625	Boost.test fail to compile with -Werror=missing-declarations on some architectures	Martin Quinson <martin.quinson@…>	Raffi Enficiaud	"Hello,

here is the error code we get:
{{{

* System::
    Centos7 with Boost 1.67 compiled from sources in /opt.
* Full logs::
    https://ci.inria.fr/simgrid/job/SimGrid-Multi/build_mode=ModelChecker,node=simgrid-centos7-x64/5662/consoleFull
* Workaround::
   simply add `bool init_unit_test();` before including boost/test/unit_test.hpp

The weird thing is that the exact same code is compiling like a charm on many other platforms that we test. We saw another instance of this bug back in May 2017, on NetBSD systems where we compiled Boost.test from the sources. At that time, we simply added the workaround described above without too much thinking.

Thanks for this great libraries,
