After the last few changes, the whole codebase now compiles and links successfully against GTK3, and I can run an experimental pterm. The config box and font selector look ugly, but the basics all seem to work. In order to compile at all, I had to manually bodge in the extra compile flag -Wno-deprecated-declarations. My plan is to fix all the uses of deprecated things, and then remove that flag. I've made GTK3 the second choice, after GTK2 but before GTK1. GTK2 is the only GTK version that produces a completely sensible build (partly because the GTK3 port is visibly unfinished, and mostly because its server-side font handling is just too slow), so it remains the first choice.
