Hi, you are right. lang/ldc is broken on 12-CURRENT. I think that some
changes into 12-CURRENT is breaking some ports

I'll be checking for your bug report (
https://issues.dlang.org/show_bug.cgi?id=17596. Maybe they implement
version feature before of 12-RELEASE. Btw I think 3 is the best option
currently.
