In case I wasn't clear, I am not opposed to having the
-munwind-check=none option, just to the amount of ugly code that was
used to implement it in the previous patch.  I think it would be foolish
to disable these checks now that we have them, but I can see that there
might be unusual cases where this might be useful.

About the .endp patch, I needed to take a closer look at that one as it
confused me.  Jan's comment said to change default name from NULL to ""
to avoid a segfault, you thanked him for the bug report, but you didn't
change this.  And since I apparently didn't receive either your original
patch or Jan's reply to it, it wasn't clear to me whether the problem
was still broken or had been fixed a different way.

I now suspect it was fixed a different way by adding the "&&
default_name" line, as I don't see a problem.
