* Makefile.in ($(NM_PROG)): Depend on demangle.o.

Browse Source 
(demangle.o): New target.
	(cplus-dem.o): Depend on it, to force compilation order when doing
	parallel compiles.

	* nm.c (print_symbol_info_{bsd,sysv,posix}): Take a bfd arg.
	(struct output_fns print_symbol_info): Ditto.
	(long_options, usage, main): Add -C --demangle option.
	(print_symname): New function, demangling if requested.
	(print_symbols, print_symbol_info_{bsd,sysv,posix}): Use it.
