Basic support for running under GDK Wayland back end. GTK 3 PuTTY/pterm has always assumed that if it was compiled with _support_ for talking to the raw X11 layer underneath GTK and GDK, then it was entitled to expect that raw X11 layer to exist at all times, i.e. that GDK_DISPLAY_XDISPLAY would return a meaningful X display that it could do useful things with. So if you ran it over the GDK Wayland backend, it would immediately segfault. Modern GTK applications need to cope with multiple GDK backends at run time. It's fine for GTK PuTTY to _contain_ the code to find and use underlying X11 primitives like the display and the X window id, but it should be prepared to find that it's running on Wayland (or something else again!) so those functions don't return anything useful - in which case it should degrade gracefully to the subset of functionality that can be accessed through backend-independent GTK calls. Accordingly, I've centralised the use of GDK_DISPLAY_XDISPLAY into a support function get_x_display() in gtkmisc.c, which starts by checking that there actually is one first. All previous direct uses of GDK_*_XDISPLAY now go via that function, and check the result for NULL afterwards. (To save faffing about calling that function too many times, I'm also caching the display pointer in more places, and passing it as an extra argument to various subfunctions, mostly in gtkfont.c.) Similarly, the get_windowid() function that retrieves the window id to put in the environment of pterm's child process has to be prepared for there not to be a window id. This isn't a complete fix for all Wayland-related problems. The other one I'm currently aware of is that the default font is "server:fixed", which is a bad default now that it won't be available on all backends. And I expect that further problems will show up with more testing. But it's a start.
