-   of the type at the time of its allocation in order to reserve space
-   for GDB's internal copy of the data.  That's why the

-   rather than struct value*s.  
-
-   However, GDB's internal history variables ($1, $2, etc.) are
-   struct value*s containing internal copies of the data that are not, in
-   general, the same as the data at their corresponding addresses in
-   the target.  Fortunately, the types we give to these values are all
-   conventional, fixed-size types (as per the strategy described
-   above), so that we don't usually have to perform the
-   'to_fixed_xxx_type' conversions to look at their values.
-   Unfortunately, there is one exception: if one of the internal
-   history variables is an array whose elements are unconstrained
-   records, then we will need to create distinct fixed types for each
-   element selected.  */
