           Summary: importc fails to link on windows x86 but successes on
                    x64
           Product: D
           Version: D2

main.d:
import test;

struct TexturePacker
{
        stbrp_context _context;
}

void main()
{
        auto res = TexturePacker();
}

test.c:

struct stbrp_context
{
   int width;
   int height;
   int align;
   int init_mode;
   int heuristic;
};

it works on x86_64, but on x86_mscoff it fails with:

error: undefined symbol: __C.stbrp_context.__inittest
