I copy-pasted this from compiler error message:
/home/rb743/dev/freebsd-riscv/lib/libc/isc/ev_timers.c:23:19: error: 'rcsid' defined but not used [-Werror=unused-const-variable=]
static const char rcsid[] = "$Id: ev_timers.c,v 1.6 2005/04/27 04:56:36 sra Exp $";
I am not sure yet why compiler set extra trailing = for some errors only
