| 66 | * what was the n_other field (an unused field) which is now the n_sect field. |
| 67 | * These modifications are required to support symbols in an arbitrary number of |

| 69 | * The values of the defined constants have NOT been changed. |

| 72 | * to relocation according to the value of their n_sect field. So for types |
| 73 | * that refer to things in sections the n_sect field must be filled in with the |
| 74 | * proper section ordinal. For types that are not to have their n_value field |
| 75 | * relocatated the n_sect field must be NO_SECT. |
