The topic has come up before:

https://lists.gnu.org/archive/html/bug-gnulib/2021-01/msg00008.html

but as far as I know nobody has tracked down what's causing the bug.

I just now looked at the wget 1.21.1 tarball and it doesn't seem to 
contain anything Gnulib-relevant. In particular it does not contain a 
copy of gnulib/m4/std-gnu11.m4. So I don't see why the problem would be 
due to a bug in Gnulib.

wget 1.21.1 was built with Autoconf 2.70, so the following post-2.70 
patches to Autoconf might be relevant:
