No, there aren't any such settings.

No, you certainly wouldn't want to have to use C mode just to get the
right sort of comments.
Some while ago, a CC Mode user requested a feature to toggle the type of
comment that M-; inserts within C Mode (i.e. /* ... */ <-> // ... \n).
I intend to write a new command to do just this, probably binding it to
C-c C-;. This will hopefully get implemented in CC Mode 5.32, which I am
hoping to release shortly after both Emacs 22.1 and GPLv3 are done.
