Wireshark-dev: [Wireshark-dev] GCC GTK3 Wireshark build warnings ?

When building GTK3 Wireshark on my Fedora system (after not having done so for a while), I'm getting many warnings similar to the following:


 CC       libgtkui_a-about_dlg.o
In file included from /usr/include/gtk-3.0/gtk/gtk.h:263:0,
                 from about_dlg.c:28:
/usr/include/gtk-3.0/gtk/deprecated/gtkstyle.h:454:43: error: identifier "and" is a special operator name in C++ [-Werror=c++-compat]
 GDK_DEPRECATED_IN_3_0_FOR(GtkStyleContext and gtk_render_background)
                                           ^

[versions: Fedora 23; GCC 5.1.1; GTK3 3.18.2]

-Wc++-compat seems to have been added in March 2013 (g557df88), so I don't know why I'm now getting the warnings (although it's been some number of months since I've built GTK3 Wireshark with GCC);
 Warnings didn't show with previous versions of GCC compiler ?
 GTK changes ??
 ???


I note that configure.ac has the following code to default to build with GTK3 in certain cases:

		#
		# No GUI toolkits were explicitly specified; pick Qt
		# and GTK+ 3.
		#
		with_qt=yes
		with_gtk3=yes
	elif test "x$with_gtk2" = "xunspecified" -a \
		  "x$with_gtk3" = "xunspecified" -a \
		  "x$with_qt" = "xno"; then
		#
		# Qt was explicitly disabled, and neither GTK+ 2 nor
		# GTK+ 3 were explicitly specified; pick GTK+ 3.
		#
		with_gtk3=yes
	fi

So: it seems we want to continue to support GTK3 ?

and thus it seems that the -Wc++-compat compile flag would need to be removed when building GTK stuff or ??

(I do note that there's been a submission in Gerritt to fix a GDK/GTK deprecation; Is this the only deprecation which needs to be fixed so that GDK/GTK DISABLE_DEPRECATED can be usued again?

Fromconfigure.ac:

	CPPFLAGS="-DGDK_DISABLE_DEPRECATED $CPPFLAGS"
if test \( $gtk_config_major_version -eq 3 -a $gtk_config_minor_version -ge 10 \) ; then
		## Allow use of deprecated & disable deprecated warnings if Gtk >= 3.10;
		##  The deprecations in Gtk 3.10 will not be fixed ...
		CPPFLAGS="-DGDK_DISABLE_DEPRECATION_WARNINGS $CPPFLAGS"
	else
		CPPFLAGS="-DGTK_DISABLE_DEPRECATED $CPPFLAGS"
	fi


Comments ?
