The following was reported by one of our users...

While fiddling around in the GNU locker, I found the following errors in
the Bison info documentation:

(1) The node Multiple Types should go Up to Semantics.  This link is
missing.

(2) The node Rpcalc Decls should go Next to Rpcalc Rules.  This link
points instead to Rpcalc Lexer.  Perhaps a better organization is:

RPN Calc - Menu	- Rpcalc Decls
    |		      |
    V		      V
   ...		  Rpcalc Rules - Menu - Rpcalc Input
		      |			    |
		      V			    V
		  Rpcalc Lexer		Rpcalc Line
		      |			    |
		      V			    V
		     ...		Rpcalc Expr

(3) The node Precedence Decl should go Next to Union Decl and Prev to
Token Decl.  These links have been swapped.
