 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
 68   * sections not just the three sections (text, data and bss) in a BSD file.
 69   * The values of the defined constants have NOT been changed.

 71   * These must have one of the N_STAB bits on.  The n_value fields are subject
 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.
