gtk 2.24's gtk.h can't be included with -Werror ?
This may be Ubuntu-specific, I am unable to check with gtk 2.24 from git at the moment.
The test case:
echo "#include <gtk/gtk.h>" > foo.c && gcc -Werror -c foo.c $(pkg-config --cflags gtk+-2.0) || echo FAIL
fails on ubuntu 19.10 using system libgtk2.0-dev; see https://bugs.launchpad.net/ubuntu/+source/gtk+2.0/+bug/1849873
Error is
