From Daniel Berlin <dberlin@redhat.com> :

	* symtab.h (SYMBOL_INIT_DEMANGLED_NAME): Initialize the symbol
 	language to auto instead of unknown, so it will try to demangle
 	the symbol.
	* symtab.h (OPNAME_PREFIX_P): Change operator prefix to correct value.
	* symtab.c (gdb_mangle_name): Properly handle C++ operators.
