Updating D 1.0

[Mike James]

What is the successful way of updating the (Windows) DM and DMD subdirectories when a D update is ready. I have just updated 1.27 to 1.29 by copying/merging the directories - it failed with the Tango library files when I did a test compilation so I have unzipped the old files and put them back as before. I have used DInstaller for the complete install previously but it's not up-to-date with 1.29 yet...

Regards, Mike.
