[Jonathan Wakely]

Tests are clean for these variations:

    unix/-std=gnu++98
    unix/-std=gnu++98/-D_GLIBCXX_USE_CXX11_ABI=0
    unix/-std=gnu++98/-m32
    unix/-std=gnu++98/-m32/-D_GLIBCXX_USE_CXX11_ABI=0
    unix/-std=gnu++11
    unix/-std=gnu++11/-D_GLIBCXX_USE_CXX11_ABI=0
    unix/-std=gnu++11/-m32
    unix/-std=gnu++11/-m32/-D_GLIBCXX_USE_CXX11_ABI=0
    unix/-std=gnu++14
    unix/-std=gnu++14/-D_GLIBCXX_USE_CXX11_ABI=0
    unix/-std=gnu++14/-m32
    unix/-std=gnu++14/-m32/-D_GLIBCXX_USE_CXX11_ABI=0

There are two FAILs for unix/-D_GLIBCXX_ASSERTIONS:

FAIL: 25_algorithms/clamp/1.cc execution test
FAIL: 25_algorithms/clamp/constexpr.cc (test for excess errors)
