In the later GTK 3 versions, a few APIs were deprecated, but I'm sticking with them in order to be able to continue building in Ubuntu 12.04, which has a rather old version of GTK 3 (3.4.2). I don't know if it's possible to suppress those warnings, but they are harmless at any rate.

I removed the -DGDK_DISABLE_DEPRECATED and -DGTK_DISABLE_DEPRECATED options, and put in -DGDK_DISABLE_DEPRECATION_WARNINGS instead. The build runs without warnings now in Ubuntu 12.04, 18.04, 19.10, and in Raspbian 10.

I originally put in the -DGDK_DISABLE_DEPRECATED and -DGTK_DISABLE_DEPRECATED options when I started work on the transition to GTK 3, but now that that code is stable, those options (which serve to flush out GTK-2-isms) are no longer needed. The -DGDK_DISABLE_DEPRECATION_WARNINGS option gets rid of the warnings about API changes in GTK 3.24, which I don't care about (yet).
