From: Stephen Hemminger [mailto:step...@networkplumber.org] Sent: Thursday, 18 January 2024 21.18The sfc base code had its own definition of static assertions using the out of bound array access hack.

For other projects using the same file, it might also need "#include <assert.h>" (containing the static_assert convenience macro for C), and possibly your workaround for toolchain issues with missing C11 macro in FreeBSD. Maybe not in this file, but somewhere. Acked-by: Morten Brørup <m...@smartsharesystems.com>
