this is a bug :-(. The ag++ option is called --real_instances, because
all ag++ options that consist of more than one word use '_' as
delimiter. ag++ should map this option to the internal ac++ option
--real-instances. However, due to a misunderstanding of the developers
--real_instances is passed unmodified to ac++, which causes an error.
As a workaround you can use ag++ to generate a parser configuration file:
ag++ --gen_config -o ac.cfg
Now add the line '--real-instances' to the configuration file.
Whenever you use ag++ additionally pass the '--config ac.cfg'.
Please note that the --real_instances/--real-instances option will
probably become deprecated with the next AspectC++ release, because the
'real-instances' parser mode will become the default and the old mode
will no longer be maintained.
sorry for this problem.
