casts to (void)

[geacc022%timevx at CIT-HAMLET.ARPA]

    Why should a cast to (void) be necessary in a statement like

	(void) printf("foo\n");

?  Why not say that the expression in the definition
<statement> = <expression>";" is automatically cast to type void?

    I put the casts to void in because they keep lint happy, but I'll
be the first to say they look ugly and impair readability...and why
are they really necessary, anyway?
