+Summary: Solve libglib2.0 problem in sketchy manner
+Date: 2021-09-22
+Version: 11.14
+Author: bgstack15
+Message:
+Warning! I have absolutely no idea what I am doing. Check https://freefilesync.org/forum/viewtopic.php?t=8780 for future developments.
+In Devuan Ceres, starting in 2021-08 with libglib2.0-0=2.68.3-2 the file icon_loader.cpp fails to compile. By removing the static_cast, this file can compile. The built application throws all sorts of GLib-GObject-CRITICIAL messages but the application operates.
+Downgrade to "deb [check-valid-until=no] https://snapshot.debian.org/archive/debian/20210801T144205Z/ unstable main non-free contrib" in /etc/apt/sources.list and install the exact libglib version necessary to compile without this patch.
+$ sudo apt-get -V install libglib2.0-0=2.66.8-1 libglib2.0-bin=2.66.8-1 libglib2.0-data=2.66.8-1 libglib2.0-dev=2.66.8-1 libglib2.0-dev-bin=2.66.8-1 libglib2.0-0:i386=2.66.8-1

+Summary: Revert 11.14 openssl 3.0.0 usage
+Author: bgstack15
+Date: 2021-09-22
+Version: 11.14
+Message: Zenju updated FreeFileSync 11.14 to use openssl 3.0.0 but my distros are not ready for that. By reverting to the 11.13 logic, the application can compile against openssl 1.1.1l as before.
