Using c-add-language is orthogonal to whether or not the new mode
derives (in the define-derived-mode) from another.

I don't think it would be correct for csharp-mode to derive from c-mode,
since the user may place settings specific to C (and inapplicable or
not desired for C#) in its c-mode-hook.
