Warnings

GCC

• gpz (x86, Linux/Gentoo, 64bit, GCC 6.4.0, GTK3) (3.2 tarball)

./configure --program-prefix=gtk3- --enable-debug --enable-native-gtk3ui --enable-debug-gtk3ui --enable-native-tools --enable-arch=native --prefix=/usr/games/ --enable-parsid --with-midas --with-resid --with-xaw3d --with-arts --with-x --enable-ethernet --with-pulse --with-sdlsound --enable-fullscreen --enable-cpuhistory --enable-static-ffmpeg --enable-static-lame

no warnings besides a bunch of ffmpeg related things that are not listed here (we dont fix them)

• compyx (x64, Windows 10/msys2, GCC 7.3.0, SDL2) (r35061)

Quite a few warnings after updating msys64, resulting in upgrading GCC from 7.3.0 to 8.2.0, though we can probably ignore the warnings about VTE.
