"David" is a proprietary product from a company called SpecOps.
It's based on the LGPL'd Wine, but the vendor has so far refused to release

Presumably now that they've shipped the product to you,
you now have the right to get a copy of the sources. Could you request
a copy from the vendor so the Wine community can check for copyright
p.s. For more about the issues the Wine community has raised, see
