[cfe-dev] Access to the field of a structure

[Sean Silva]

Other than just overriding VisitRecordDecl (instead of VisitDecl) what
you've done seems to make sense. Sorry about the confusion; I thought for
some reason you already had a reference to the TypedefDecl and didn't want
to do another AST visitation to find the struct.
