I'm getting it now, hoping to have some time for barcode soon.

Usually it's not a matter of being completely unaware of other code.
Unless you singed your mindshare away (like some vendors require before
showing the code).  If that code was only under a copyright license (no
contract explicitly signed by you or your employer, I mean), then you
can reimplement things yourself, as long as they are not copied.
Given the framework of GNU barcode (the intermediate encoding and so on)
I doubt that your port would be a plain copy.

Yes that would be interesting. Thanks
