+Subject: [PATCH] if ptr to member var. is defined, ensure the class is
+ complete
+
+... because MSVC represents pointers to member as variable size,
+depending on context (e.g., multiple inheritance). So it can happen that
+the size of the pointer in the header (where the class is only
+forward-declared) differs from the size of the same pointer in an impl.
+file (where the class is complete).
