Yes. I was proposing ditching the third class.

That would be reasonable.

I believe we did this to avoid gratuituous use of gdb extensions, but since gdb extensions are the norm now, there isn't much point in doing this. This lets us eliminate have_used_extensions.

I see that there are a couple of places that test use_gnu_debug_info_extensions, but fail to set have_used_extensions. Perhaps this is what you were thinking of earlier? This is arguably a bug, but eliminating have_used_extensions makes this a moot point. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
