I tried it and it works _perfectly_ for me, but instead of .a I
compiled the C++ files to .o

    g++ -c cpp1.cpp
    g++ -c cpp2.cpp
    dmd cpp1.o cpp2.o file.d -L-lstdc++

(I had to comment the printf in cpp1.cpp)

Running the program prints this output:

    Testing callinf C++ main from D

    cbin2 c++ library called from:cbin.cpp

I'm on Kubuntu 12.04 64bits, using DMD v2.063.2
I have the following libstdc++ packages installed
As shown by   dpkg -l libstd*|grep ^ii

    libstdc++6          4.6.3-1ubuntu5
    libstdc++6-4.4-dev  4.4.7-1ubuntu2
    libstdc++6-4.6-dev  4.6.3-1ubuntu5

G++ version is:  g++ (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3

ldd on the executable shows that it's using these libraries:
        linux-vdso.so.1 =>  (0x00007fff989ff000)
        libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f9c0cbb7000)
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f9c0c99a000)
        librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007f9c0c791000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f9c0c57b000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9c0c1bc000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f9c0cedb000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f9c0bebf000)


Hope that any of this was useful to you!
