Based on an inspection of the libc++ source, I've pushed a tentative fix
to develop - it looks like C++11 (and later) headers may be at least
somewhat usable in C++03 mode. The catch is that if your tests assume
that the presence of <array> indicates a fully functioning version with
all the C++11 features then your test will certainly fail. In that
situation you may need to check for initializer lists / constexpr /
noexcept etc separately.
Currently the change is restricted to <array> and <forward_list> as
these need relatively lightweight compiler support, most of the other
headers are quite tied into C++11 language features.
