    Because the dll - backend is loaded recursivly about 100.000 times...
    actually dll doesn't segfault, but sooner or later one of the backends
    segfaults when allocating new memory.

    Ok, might be... I've another fix: instead of linking libsane.* to
    sane/libsane-dll.* we could copy libsane-dll.* to libsane.* and remove
    the dll-backend from the lib/sane/ directory. This way, the dll-backend
    can't load itself (because it isn't present as a backend)

    what about this?
