Well that's what is already done in mi-main.c, although admittedly the other
mi files use error.  More importantly, how do you propagate two messages
back up the stack when gdb_exception only allows one?

(top-gdb) ptype e
type = struct gdb_exception {
    enum return_reason reason;
    enum errors error;
    const char *message;
}
