digger fails to build D on windows

[Moth-Tolias]

when attempting to build, digger fails with the following error [some sections removed for brevity]:

it appears that something [make?] is calling xcopy with invalid arguments.

[Moth-Tolias]

seems like this is the result of an incorrectly configured makefile in the outdated, archived version of druntime at https://github.com/dlang/druntime... fixing it in the downloaded repo and running digger rebuild just results in another error later down the line however - perhaps digger needs to be adjusted to take the dmd/druntime merge into account?

[CyberShadow]

Yes and also there is a bug in the DMD or Druntime makefiles, which attempt to provide backwards compatibility but fail to do so in this case.
