These represent omissions from the dwarfdump
tag_tree.list  file.

In other words, dwarfdump is wrong to warn.

Since I've left SGI future modifications will be coming from me,
not SGI (it is open source and SGI knows I intend to support
dwarfdump/libdwarf and SGI has no problem with me doing this).
I'm going to build a subversion source tree to track changes, but
won't export the tree (sorry), I will just continue issuing updated source.

I'm afraid the *.list files for checking are not very up to date.
I welcome suggestions for improvement (such as the one in this note).
(Thanks Marcel).
