Why, this is a constant array so it is removed right?

IIRC, this was intentional because people had a habit of writing RCS
"$ID:" strings at the top of files and wanted to find them again in
the executable to identify which files exactly were linked together.
You may find relevant discussions somewhere in the archives.
