A signal handler is required to have a signum parameter that is an integer. This patch is used by buildroot for GCC 15.x compatibility: https://gitlab.com/buildroot.org/buildroot/-/commit/6fd3e498af1bf837f3318eb0d47f27ac6901e7dc Signed-off-by: Charlie Jenkins <charlie@rivosinc.com> Signed-off-by: Bernd Kuhls <bernd@kuhls.net>
