I'm looking at cleaning up a few compile nits and I'm wondering what the officially approved way of silencing "may not be used" warnings: int foo(int flag) { int j; if (flag) j = 1; /* * This noop statement is enough to confuse the optimiser so it * forgets that j is initialised iff flag != 0 */ flag = !!flag; if (flag) return j; return 0; } Us humans can see that j is not used without being set, but cc can't. How do I remove this warning in a style(9)-compatible way? To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
