* Added Create_errhandler for MPI::File * Make errors_throw_exceptions a first-class predefined exception handler, and make it work for Comm, File, and Win * Deal with error handlers and attributes for Files, Types, and Wins like we do with Comms - can't just cast the callbacks from C++ signatures to C signatures. Callbacks will then fire with the C object, not the C++ object. That's bad. Refs trac:455 This commit was SVN r12945.
