[Chicken-users] getopt-long complains about missing property

[Markus Klotzbuecher]

Dear All,

I'm get an error with the getopt-long egg. It is reproducible with the
example on the getopt-long egg page:

Error: invalid getopt-long option property: required?

       Call history:
       <syntax>   (getopt-long (quote ("my-prog" "-vk" "/tmp" "foo1"

       error                                            <--

According to the docs required? should be a valid property.

I'm on debian, chicken Version 4.6.0, getopt-long v1.12, matchable
v3.1.

Thanks in advance for any help!
