Subject: [boost] Strange libstdc++ versions in travis-ci testers

Hi Everyone,
Maybe someone could help me understand the configuration on the travis-ci
testers. Whenever I push a new commit I get a number of failures from
travis-ci about missing std::is_trivially_default_constructible from the
standard library; like here:

Some tests with Boost.Predef indicate that they are clang compiler 3.X, and
clang 5 with libstdc++ of strange version nubers: macro BOOST_LIB_STD_GNU
gives values 450400026 and 460700026, which would correspond to releases
2015-04-26 and 2016-07-26, but when I look at the release notes for GCC
there are no releases mentioned of these dates:

Maybe someone knows what versions of libstdc++ these are? Or maybe I am
missing something obvious?
