As usual, thank you for the comments.

Sure; I was just moving these, but let's take the opportunity to
improve it further.

Sounds good.  I expect it will stay on dwarfstd.org for a while; it's
had several homes in the last few years.

Interesting, I didn't know about those.  I like the block
of C code -- if you want to check whether something is a sentinel
frame in GDB, you type get_frame_type (f) == SENTINEL_FRAME -- but
@equiv will do nicely too so I'll use that.

That's how most of the gdbint manual is currently arranged - one node
per chapter, except for a few more substantial ones.  I can move the
new sections into nodes if you think that's better.

Done.

Fixed.

Also fixed.

I'll repost the final patch in a little while.
