+Message: Use the following command to get this old contents. Zenju must be using some newer definition of -std=c++2a than what Devuan Ceres provides as of 2020-05-17, and probably wxwidgets. This is the 10.23 code for these files.

+Unfortunately with the removal of the wxWidgets-gtk2 code from Debian, we are stuck using all available at approximately November 1, 2019 snapshot of Debian: https://snapshot.debian.org/archive/debian/20191101T211023Z/pool/main/w/wxwidgets3.0/
