Hi.
This is follow up of PR87562 which was introduced by commit that fixed the
issue.
Unfortunately I can't reproduce that with -E -C so that one needs to do
following:
$ wget https://github.com/aqbanking/gwenhywfar/archive/4.20.1.tar.gz
$ tar xvzf 4.20.1.tar.gz
$ cd gwenhywfar-4.20.1
$ autoreconf -ifv && ./configure --with-guis && make -j8
...
