--- Comment #8 from Dima Ryazanov dima@gmail.com 2010-02-05 22:45:50 --- I'm seeing an interesting behavior now. This is just what I wanted in this bug report, but I really doubt it's intentional:
Under HKEY_CURRENT_USER/Environment, create a string "FOO" with an empty value. Run "FOO= wine /c cmd set". Now, you see just the Windows environment, with no UNIX variables.
(What I expected was the usual environment, but without the FOO variable.)
Should I file a new bug for this?
