<pre>Empty structs have 4-byte size in "-cxx-abi microsoft" mode, see the
test/Sema/empty1.c test.
But the standard says they should be 0 bytes. MSVC rejects empty structs in C
mode, so I'm not sure entirely what layout it would give them.
And it's weird that -cxx-abi affects these sizes because we're not in C++ mode.</pre>
