63  * This file gives definitions supplementing <nlist.h> for permanent symbol
64  * table entries of Mach-O files.  Modified from the BSD definitions.  The
65  * modifications from the original definitions were changing what the values of
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.
70  *
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.
