The patch needs to be updated for other architectures as well...

With clang, including an extern "C" header with an empty struct in C++ code results in a build failure:

empty struct has size 0 in C, size 1 in C++

So for the sake of compatibility, the struct should have a size of 1 unconditionally when building with clang. Attaching patch.
