Subject: [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).
Regards,
Ian McCulloch
