Where is the dead symlink located?
In the same directory as the file being edited.
If one user opens a file with mcedit for editing and another user
does the same with mcedit should he get a message about this fact?
Yes.
The mc version is 4.5.51 wiht RedHat 7.2
That version doesn't support locking. Locking support was
added starting with MC 4.6.0.
I've updated MC to 4.6.0 on the RedHat 7.2 system, but there is still no
dead symlink and
no message editing a file already opened by somebody else.
I've tried the same with MC 4.6.1 on a gentoo system, but also no symlink
and no message.
Is there a special option to activate locking support, or is there
something else to do?
