OK.  So [4] is a permissive license for all files in the directory.
This may seen odd, coming from the FSF, but they encourage this is
some cases, such as when the code is very small, or where the code
promotes the use of an open standard that competes against a
proprietary standard.

The Apache practice is documented here.  Look under "Treatment of
Third-Party Works".

http://www.apache.org/legal/src-headers.html

One of the steps says, "Do ensure that every third-party work includes
its associated license, even if that requires adding a copy of the
license from the third-party download site into the distribution."

It is not clear to me how we apply that step in this case:

1) Do we copy that license file into the same directory as ksc5601.h?
But the license is written very poorly, "This notice applies to the
files in this directory".   We might have it in a directory that has
other files that were not originally in the same directory.  This
seems like a bad idea.

2) Do we add the license to the specific files that we've copied?
That is your proposal.

3) Or do we not touch the original file, but simple put the license
text in our NOTICE.txt

Maybe best is #2, but also put a comment in the source code where you
document the provenance of the file,  giving the facts you gave above:
that the file is from this URL, that the license is in this other
file, and the text of the license is as follows, etc.
