- we have to be able to attach a string to an error class, not just to an error code - according to MPI-2 the attribute MPI_LASTUSEDCODE has to be updated everytime you add a new code or a new class. Thus, you have to have single list for both. Thus, we got rid of the error_class structure. In the error-code structure, we can distinguish whether we are dealing with an error code or an error class by looking at the err->code element of the structure. In case its value is MPI_UNDEFINED, the according entry is a class, else it is an error code. All predefined error codes have the code and the class field set to the same value. The test MPI_Add_error_class1 passes now. Fixes trac:418 This commit was SVN r12764. The following Trac tickets were found above: Ticket 418 --> https://svn.open-mpi.org/trac/ompi/ticket/418
