Well, knowing you have to look would be good!
There seems to be a lot of separate definitions of these structures
that are not cross referenced (even by comments), and don't even have a
single file whose compilation fails when they don't match.
(I've cross commented some of them now, and most of the ones (except
in gdb) for amd64 are now defined from data in one .h file.)
