https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: sys-libs/ncurses-6.4_p20230401 has implicit function declarations in configure logs (MUSL-SYSTEM). Discovered on: amd64 (internal ref: tinderbox_musl) NOTE: (MUSL-SYSTEM) in the summary means that bug was found on a machine that runs MUSL libc but this bug MAY or MAY NOT BE related to musl.
