Seen style(9) -- a friend pointed it out to me before I started working on the
kernel.

...and I was prototyping. Like this :

static	void		msctimer();

I changed it to :

static	void		msctimer(void);

... and the problem went away. Funny, I have never received that watning
before, and I have been using C (with prototypes like that) for many years.
