+
+ Get rid of some platform-specific functions examining window
+ system and its capabilities. This is a partial rework of the
+ 2013-04-05 change.
+ * lisp.h (have_menus_p): Remove prototype. This function is
+ replaced with platform-independent window_system_available.
+ (check_window_system): Move to...
+ * frame.h (decode_window_system_frame, window_system_available):
+ ...here, add new prototypes.
+ * frame.c (window_system_available, decode_window_system_frame):
+ New functions.
+ (check_window_system): Platform-independent now.
+ * xterm.h (x_in_use): Remove declaration.
+ (check_x_frame):
+ * w32term.h (check_x_frame):
+ * nsterm.h (check_x_frame): Remove prototypes. This function
+ is replaced with platform-independent decode_window_system_frame.
+ * msdos.c (have_menus_p): Remove.
+ * nsfns.m (check_window_system, have_menus_p, check_ns_frame):
+ Remove platform-specific functions. Use check_window_system,
+ decode_window_system_frame and check_ns_display_info where
+ appropriate. Minor style and comment tweaks.
+ * w32fns.c (w32_in_use, check_window_system, have_menus_p)
+ (check_x_frame): Likewise.
+ * xfns.c (x_in_use, check_window_system, have_menus_p, check_x_frame):
+ Likewise.
+ * fileio.c, fns.c, font.c, fontset.c, image.c, menu.c, nsmenu.m:
+ * nsselect.m, nsterm.m, w32font.c, w32menu.c, xfaces.c, xgselect.c:
+ * xmenu.c, xselect.c: All related users changed.
