The license status listed for each piece of software is the "primary" license under which it is distributed. In several cases, parts of the software package may be distributed under other licenses -- potentially even non-copyfree licenses, as in the case of all BSD Unix items currently in the Operating System category, which at minimum include the GNU Compiler Collection.
