I second branching if -v1 doesn't perfectly imitate the state of the 1.0 compiler. I also second the motion for putting D development and sources on SVN - in spite of my feelings for SVN nomenclature. If the powers-that-be agree, then I would suggest moving it to SVN, taking the 1.0 release as-is, and then carefully merge-diff'ing it up to current for bug fixes.
