digitalmars.D - Self-hosting D compiler -- Coming Real Soon Now(tm)

It's finally happening! As some of you may know, DDMD (i.e., dmd written
in D, currently via autotranslation) has been in the works for a while.
And now, we have the first pull request to replace one of DMD's C++
source files with D code:

	https://github.com/D-Programming-Language/dmd/pull/3970

Before the compiler team pulls this, however, we need to sort out some
issues, such as:

- How to make a nice transition for people who follow git HEAD (whose
  setups will inevitably fail once the above PR gets pulled, since it
  will likely be unable to find a working D compiler in order to build
  itself);

- Providing clear instructions on how to build a self-hosting compiler;

- Providing working dmd binaries from which may be used to bootstrap the
  process of building dmd;

- Decide on policy on how many previous releases the current codebase
  must be buildable on (currently, it's just the previous release, as I
  understand it);

- etc.. (I'm sure there are other issues I didn't think of.)

So this thread is to start discussion to sort these things out before we
move ahead.

Destroy!

Install appropriate dmd release.  Set HOST_DC to point to it.  Run makefile 
as usual.

The release zips are the source of working D compilers.  There is no work 
that needs to be done here.

   must be buildable on (currently, it's just the previous release, as I
   understand it);


It will be at least the current HEAD and previous release.
