I think it's currently v2.076. I don't know where that is 
documented.

I Had the same experience on Linux. It was not possible to build 
dmd with a predecessing version between version 2.074 and version 
2.08?. I had to download a binary of higher version to build the 
newer  compiler or else I would have been stuck on 2.073. It's a 
rather annoying as we have really strange rules in place that 
normally do not allow to install binaries from Internet.

Another option would be to use 2.074 to compile 2.075, then use 
that to compile 2.076, and so on...of course using the release 
versions is arbitrary, and may not be granular enough and will 
likely be too granular in most cases.

One really cool thing about D though is that now DMD is 
completely in D, if you compile it with the `build.d` script it 
only takes about 20 seconds to compile the whole thing.  The 
Makefile still takes longer because it's using many invocations 
of the compiler though.

That was the issue this process works until 2.78.2 (sorry the 
numbers were off in my first message [1]).
It requires at least 2.79.1 to build anything after 2.78.2 on. 
This means there is a gap in the "build chain".

Wait I remembered wrong.  The Makefile takes about 20 seconds to 
build.  The `build.d` script takes about 7 seconds to build.  
Just confirmed it on my machine.

The firs time, otherwise it takes more 2 to 3 seconds because 
most of the times the objects are cached.

The easiest solution for this is to set AUTO_BOOTSTRAP=1 when 
building DMD as this will automatically download a working 
bootstrap compiler. 2.079 at the moment.
