--- Comment #1 from jiki at red.email.ne.jp ---
Unfortunately I doubt that it can be included in 2.070 release.

At least, it is mandatory to fix the following problems,
otherwise they would yield critical RUNTIME errors.

- extern (Windows) missed : wrong calling convention
   For instance: the aliases of callback functions in commctrl.d and wingdi.d.
- API update for x64: mostly modifications for the pointer size change
   For instance: https://github.com/Rayerd/dfl/pull/50/commits

I tried to fix the former and gave up after a number of errors come.
I have no idea to go over...
