 ** Emacs now supports being built with pure GTK.
-To use this option, make sure the GTK 3 and Cairo development files
-are installed, and configure Emacs with the option '--with-pgtk'.
-Unlike the default X and GTK build, the resulting Emacs binary will
-work on any underlying window system supported by GDK, such as Wayland
-and Broadway.  We do not recommend that you use this configuration,
-unless you are running a window system that's supported by GDK other
-than X.  Running this configuration on X is known to have problems,
-such as undesirable frame positioning and various issues with keyboard
-input of sequences such as 'C-;' and 'C-S-u'.
