<div dir="ltr">Sorry! I thought I got this build error when making HEAD, but I don&#39;t. It builds fine.<br>

However, if I just cherry-pick this simple commit onto HEAD<br>

then I do get this error, which is very puzzling. I did a make maintainer-clean in between.

I tried all of clean, distclean and maintainer-clean, followed by the<br>
usual build process. The issue remains.<br>
