===============================================================================
Note 1: When both __XCOFF32__ and __XCOFF64__ are defined, but
__XCOFF_HYBRID__ is not, the macro "n_nptr" is not defined.
The n_nptr definition is not very useful when compiling in
64-bit mode.
Note 2: For an XCOFF64 file, the n_type field may only have the values
0 (if the symbol is not a function) or 0x0020 (if the symbol
is a function).
Note 3: All the fields containing "x_auxtype" refer to the same byte
of the auxiliary symbol table entry.
Note 4: The XCOFF64 equivalent for x_csect.x_scnlen is the concatenation
of x_csect.x_scnlen_hi and x_csect.x_scnlen_lo.
Note 5: When _AUX_EXCEPT and _AUX_FCN auxiliary symbol table entries
exist for the same primary symbol table entry, the x_fsize and
x_endndx fields of the two entries should have the same values.
Note 6: Field names not listed in the table above are obsolete and are
not used in the current release of AIX.
