- replace sprintf with snprintf - use calloc() to avoid malloc(n * m) overflows - NetBSD PR 36831: In setfval(), ensure that arithmetic never yields a negative zero result. - Restore the traditional (FreeBSD <= 2.x) behavior of trapping FPEs. With this patch we pass mawk's fpe_test. PR: 125348 Submitted by: "Pedro F. Giffuni" <pfgshield-freebsd@yahoo.com>
