It appears that BenF’s source code conversion to other compilers has been solved as discussed in topics such as viewtopic.php?f=12&t=1728&hilit=git&start=10

A lot of time has passed and maybe now BenF would report his general intentions about future open source code releases or his intent not to release future open source code revisions. Whether BenF provides future open source code or not, we all owe him our gratitude for the excellent binaries that he has provided since V3.0
