This procedure runs through the native entries in a coff symbol table

particular these are:
|

||
strtag, entag and untags have an auxent endindex which points to the
|
||
first syment after the .eos. This is simple to do, we just keep a
|
||
pointer to the symbol with the most recent pending strtag and patch it
|
||
when we see the eos. This works since coff structs are never nested.
|
||
|
||
ISFCN type entries have an endindex which points to the next static or
|
||
extern in the table, thereby skipping the function contents.
|
||
The coff book says that an ISFCN's tagindex
|
||
points to the first .bf for the function, so far I havn't seen it
|
||
used. We do this using the same mechanism as strtags.
|
||
|
||
Each file entry has a value which points to the next file entry,
|
||
the last file entry points to the first extern symbol in the table
|
||
which is not an ISFCN.
|
||
|
||
Each .bb entry points to the matching .eb entry, but these are nested
|
||
so we keep a stack of them.
|
||
|
||
The tagndx of .eos items points to the strtag attached to them, this
|
||
is simply the last_tagndx again.
|
||
|
||
The tagndx of items with type strtag point to the defining struct.
|
||
This bit is complicated; We know that a struct ref and def must be
|
||
within the same file, so all the natives will be in the same vector.
|
||
This means that we can subtracts two pointers and get the index
|
||
differences between to items, used to work out the true index of the
|
||
target.
|
||
|
||
We store in the name field of each syment the actual native index

applied so we can dig it out through a pointer. */

backwards to find the previous C_FILE, or choke if you get to a C_STAT
