Bug ID: 56114
           Summary: winecfg allows a cdrom drive path to be inside of the
                    WINEPREFIX
           Product: Wine
           Version: 9.0-rc3
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

To reproduce:
$ rm -rf ~/wine-tmp/
$ mkdir ~/wine-tmp
$ export WINEPREFIX=~/wine-tmp
$ cd ~/wine-tmp
$ mkdir cd
$ touch cd/file.txt 
$ winecfg
choose drives -> add -> D: -> OK now a new drive is added with / as the path
copy and paste this into the path and click ok:
~/wine-tmp/cd/
$ ls ~/wine-tmp/dosdevices/d: 
/home/cedric/wine-tmp/dosdevices/d:
$ cd ~/wine-tmp/dosdevices/d: 
bash: cd: /home/cedric/wine-tmp/dosdevices/d:: No such file or directory

Wine should refuse to accept a path for the CD when it's in the WINEPREFIX
Bonus points for presenting a prompt to the user explaining the limitation.
