The ParseStructUnionBody function was separately keeping track of the field decls for historical reasons, however the "ActOn" functions add the field to the RecordDecl anyway. The "ParseStructDeclaration" function, which handles parsing fields didn't have a way of handling what happens on an anonymous field, and changing it would alter a large amount of objc code, so I chose instead to implement this by just filling the FieldDecls vector with the actual FieldDecls that were successfully added to the recorddecl .
