Description

dmd.2.0xx.x.windows.zip seems to use backslashes for directory separators (unlike dmd.2.0xx.x.zip), which does not seem to be compatible with all Zip programs. For example, compare the directory listing of the root of dmd.2.065.0.zip with that of dmd.2.065.0.windows.zip in Midnight Commander:

This problem seems to occur in all dmd.2.0xx.x.windows.zip files released to date.
