-If you want to make sure that your program doesn't use any deprecated
-functions, you can define the preprocessor symbol GTK_DISABLE_DEPRECATED
-by using the command line option <literal>-DGTK_DISABLE_DEPRECATED=1</literal>.
+Deprecated GTK+ functions are annotated to make the compiler
+emit warnings when they are used (e.g. with gcc, you need to use
+the -Wdeprecated-declarations option). If these warnings are
+problematic, they can be turned off by defining the preprocessor
+symbol GDK_DISABLE_DEPRECATION_WARNINGS by using the commandline
+option <literal>-DGDK_DISABLE_DEPRECATION_WARNINGS</literal>

+The older deprecation mechanism of hiding deprecated interfaces
+entirely from the compiler by using the preprocessor symbol
+GTK_DISABLE_DEPRECATED is still used for deprecated macros,
+enumeration values, etc. To detect uses of these in your code,
+use the commandline option <literal>-DGTK_DISABLE_DEPRECATED</literal>.
There are similar symbols GDK_DISABLE_DEPRECATED,
GDK_PIXBUF_DISABLE_DEPRECATED and G_DISABLE_DEPRECATED for GDK, GdkPixbuf and
GLib.
