I can't remember exactly the problem - it was some time ago - but I think it might have been related to console input. Either it was built for Windows console and didn't quite handle mintty LF, EOF and line wrapping, or the other way around. Usually you can wrangle programs into working by using winpty, but it still didn't operate quite as smoothly as dc did under UNIX (or Cygwin). In the end I mostly ended up invoking it in a pipeline instead of interactively. Fortunately your dc worked out of the box with winpty a couple years back, and - to my delight - I just discovered the latest version works both in a modern Windows console and Git Bash mintty as well, without any winpty wrapping. Great work, thank you!
