RCS markers (RCSid) are wrapped inside #ifdef to avoid spitting out
compiler warnings, when they aren't used. You can find RCS markers
everywhere inside *BSD repositories (I can speak about OpenBSD and
NetBSD source code I'm familiar with). If you don't plan to use them,
you can remove them safely.
