The leading "4" comes from the Pascal length of the string.  If you
include this check, you should match against the full string,
verbatim, to avoid false negatives.

Or the FPC folks could alter the copyright notice to indicate that
this is a reimplementation.  In a certain sense, this is not even a
false positive because the code appears to be rather literal
translation.  There are other ways to detect zlib copies, but those
would detect this one, too.
