Comment:

 I usually define a mapping table to map my command line options to the
 string value, e.g.:

 {{{

 enum MyOptions {
    HELP = 0,
    VERSION,
    INPUT
 };
 string options[] =  { "help", "version", "input" };


 ... /// usage
 if (vm.count(options[HELP]))

 }}}

 Within my code I then use only the enum type. Errors are then detect
 during compile time.

 You can define this options[] array for each platform you want to support
 and were it is different to the 'reference' array.

 I sgguest to keep this type of mapping in the client code. Currently there
 is no 'special' handling for any options, all handled in the same way and
 I would like to keep this behaviour.

 My suggestion is to set on "wont fix".

 Thanks,
 Sascha
