/*
GCC 5.1 introduced new implementations of std::string and std::list:

https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html

This causes e.g. std::string to be actually defined as
std::__cxx11::string.

On machines with GCC 5.1, this manifests as a linker error when
running the cppa.d / cppb.cpp test:

cppa.o: In function `_D4cppa6test14FZv':
cppa.d:(.text._D4cppa6test14FZv+0x11): undefined reference to `foo14a(std::string*)'
cppa.d:(.text._D4cppa6test14FZv+0x18): undefined reference to `foo14b(std::basic_string<int, std::char_traits<int>, std::allocator<int> >*)'
cppa.d:(.text._D4cppa6test14FZv+0x3a): undefined reference to `foo14f(std::char_traits<char>*, std::string*, std::string*)'
cppa.o: In function `_D4cppa7testeh3FZv':
cppa.d:(.text._D4cppa7testeh3FZv+0x19): undefined reference to `throwle()'
collect2: error: ld returned 1 exit status
--- errorlevel 1

When the .cpp file is compiled with g++ 5.3.0, the actual function
signatures in the cppb.o object file are:

foo14a(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >*)
foo14b(std::__cxx11::basic_string<int, std::char_traits<int>, std::allocator<int> >*)
foo14f(std::char_traits<char>*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >*)

Fortunately, it is easily possible to disable the new feature
by defining _GLIBCXX_USE_CXX11_ABI as 0 before including any standard
headers.
