That is the problem, you're (for whatever reason) getting that version
for <sys/cdefs.h> instead of the NetBSD version (which defines RCSID,
indirectly).

You appear to be attempting to use a NetBSD specific source file while
compiling a linux API set of code, that can't really work.

If you need to continue this way, just delete (or comment out) the
RCSID line - it is just for version identification of the object file,
it doesn't do anything necessary to make the code work.
