ade-tests-custom: Build with --disable-Werror
Cross building helloworld-simple-agent
with GCC 8 from v2019dev0 against GLib
2.50.2 as shipped in 18.06 leads to failure due to -Wextra
turning on the
new -Wcast-function-type
warning and AX_COMPILER_FLAGS
making it fatal by
turning -Werror
on.
The fix for GLib landed in 2.56.0: https://gitlab.gnome.org/GNOME/glib/commit/c1f5e52844c
In order to still build against the old 18.x sysroots, pass --disable-Werror
to the configure command.
See https://gitlab.gnome.org/GNOME/gnome-terminal/issues/96#note_480034
instead for the best way to silence the warning using a cast to GCallback
should the issue be in your own code.
