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

+
+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. */
