-   We used to just use the REGISTER_NAMES macro, from GDB's

-   meant that libsim.a had only a compile-time dependency on GDB;
-   using reg_names directly means that there are now link-time and
-   run-time dependencies too.
-
-   However, the GDB PPC back-end now modifies the reg_names array when
-   the user runs the `set processor' command, which affects the
-   meanings of the register numbers.  So the sim needs to see the
-   register names GDB is actually using.
-
-   Perhaps the host_callback structure could contain a pointer to the
