- newlib was default to XOPEN MODE before 2018/12/6[1], but newlib decide to remove XOPEN mode SVID3 mode, and change the default IEEE mode. - The problem is IEEE won't set errno on several math function, so build with POSIX mode would be better for newlib. - For newlib nano, we might able to build with _IEEE_LIBM in future to reduce code size, and improve performance.
