+dnl Check for glib. This differs from other library checks in that
+dnl Emacs need not link to glib unless some other library is already
+dnl linking to glib. Although glib provides no facilities that Emacs
+dnl needs for its own purposes, when glib is present Emacs needs to
+dnl use primitives like g_main_context_query to avoid clashing with
+dnl glib at a low level.
+dnl
dnl Check this late, since it depends on $GTK_CFLAGS etc.
