Thanks, but I find the current documentation clear enough:

 -- Function: make-symbol name
     This function returns a newly-allocated, uninterned symbol whose
     name is NAME (which must be a string).  Its value and function
     definition are void, and its property list is ‘nil’.  In the
     example below, the value of ‘sym’ is not ‘eq’ to ‘foo’ because it
     is a distinct uninterned symbol whose name is also ‘foo’.

          (setq sym (make-symbol "foo"))
               ⇒ foo
          (eq sym 'foo)
               ⇒ nil

 -- Function: gensym &optional prefix
     This function returns a symbol using ‘make-symbol’, whose name is
     made by appending ‘gensym-counter’ to PREFIX.  The prefix defaults
     to ‘"g"’.

I see nothing that could be gained by adding any explicit sentence
about the difference, since that would simply be a rewording of what
is already said right there.

So I'm closing this bug report.
