dmd build instructions from source don't work anymore

[Timothee Cour via Digitalmars-d]

I found the culprit by bisection:
hash: 50b7697...

HEAD is now at 50b7697... Merge pull request #3970 from yebblies/idgend2

https://github.com/D-Programming-Language/dmd/commit/aa8a7b3dcf985c8332783961c1dd7bc598ec36c5

it builds fine right before this, and fails with this
