Do the .d files contain the correct "#line" token sequences?
I.e. something like '#line 6 "myfile.dw"' (_including_ the file name)?
If so then DMD _should_ generate the correct debug info (according to 
http://www.digitalmars.com/d/lex.html#specialtokens).
I haven't tested this, among other things because it probably wouldn't 
mean much since I'm not using Windows and debug info is different on Linux.
