Thanks for reporting this.

The variable is used only in a build that supports some GUI display.
However, I don't want to complicate our code to pacify a compiler, so
you'll need to ignore this one.

Fixed.

This is a variable, so the compiler has no business suggesting such
changes.  I left that alone.

Fixed.

Fixed.

This warning will go away when the next version of Texinfo is
released, they decided to lift this restriction.

With that, I'm closing this bug.
