bug#23640: 25.1.50; Getting rid of compiler warnings

Your patch seems reasonable to me.

The reason I chose the name UNUSED is that I had in mind
it would stand for just the initial value (without the =).
But then I imitated the suggestion to include the =.
You're right that name UNUSED is not appropriate for that.

So I suggest

  char *ident_start = UNUSED;

and so on.  That should make it very clear, and the name
fits what it does.
