[AD] Static linking requires libstdc++ with mingw?

[Elias Pschernig <elias.pschernig@xxxxxxxxxx>]

Using mingw, I get errors like this:

gcc.exe -W -Wall -g -DDEBUGMODE=1 "CMakeFiles/ex_bitmap.dir/ex_bitmap.c.obj"
    -o ex_bitmap.exe -Wl,--out-implib,libex_bitmap.dll.a

Does anyone else get the same?

Adding -lstdc++ fixes the problem for me, so we could simply add that to
the examples when using the static build in Windows.

But apparently my DirectX libraries are a bit broken (as hinted to by
those 4 warnings). So do we logically have to add -lstdc++ if the static
library sources are C++ (d3d_disp.cpp and d3d_bmp.cpp), or should I try
finding a better set of DX libraries for mingw? Or something else?
