	No its not.  The guidelines about casts to void are raised in the
context of not "placating lint" which could make your program "ugly".

	Lint requires you to cast to void >every single function call<
which returns a value which you don't use.  (I agree that's ugly.)

	My use of void casts is in the context of silencing a gcc
warning, not lint.  The gcc documentation itself suggests using void
casts for this warning, and we have an established practice of doing so.
