I've never seen such an error. Do you have the details?

For historical reasons, the Windows makefiles take a different 
approach in many aspects. One important point is that they are 
limited to the feature set of the Digital Mars make 
implementation, which is extremely basic.

For a build tool which can build D and all its components from 
source today, you can have a look at Digger:
