What is the long-term plan for the current DMD backend? I've noticed the first steps towards 64-bit support were just checked in today (excitement to the extreme). However, the backend is under such a restrictive license (which I understand Walter is not free to change) that it has a "bus factor" of 1. If Walter were to stop maintaining it, noone else would be able to, if I understand the licensing issues correctly.
Is there a chance of these licensing issues being cleared up so that the backend can be released under a more permissive license? If not, while I understand Walter's decision to use a backend he was familiar with in the beginning, it seems like we should abandon such a heavily encumbered backend now that it needs serious work.
