It sounds good to me.

Daniel, is this the result?

        * minsyms.c (add_minsym_to_demangled_hash_table): New function.
        (install_minimal_symbols): Fix demangled symbol problems caused
by
        using add_minsym_to_hash_table for the demangled names, which is

Just a small nit: this is a static function in minsyms.c, yet
it's declared extern in symtab.h.  Gives a new -Wall warning.

I've just committed the change below.  (This change was for AIX 4.3.)

	* gdb.base/pointers.c (usevar): New function.
	(main): Make sure that global variables v_int_pointer2, rptr,
	and y are all referenced someplace in the program by calling
	usevar() on them.  [Some linkers delete symbols which are
	never referenced.  The space remains, but there's no way to
	get a (symbolic) handle on the variable from the debugger.]
