[Boost-users] [program_options] positional options starting with a '-' sign

Hi, I have an app using program_options, which has various optional arguments, followed by any number of floating point numbers, which are read as positional options. A user just pointed out that it fails with an 'unknown option -0' error if any of those positional options are negative, because it tries to interpret a number like "-0.34" as an option. Is there a way to treat unregistered options as positional arguments? allow_unregistered() doesn't quite do it - it doesn't give an error anymore but neither does it treat "-0.34" as a positional option (even if it is not the first positional argument).
