"Return (X-MIN Y-MIN X-MAX Y-MAX) for the frame containing WINDOW.
If WINDOW is nil, return the edges for the selected frame.
-(X-MIN, Y-MIN) is the zero-based coordinate of the top-left corner
+\(X-MIN, Y-MIN) is the zero-based coordinate of the top-left corner
of the frame; (X-MAX, Y-MAX) is the zero-based coordinate of the
bottom-right corner of the frame.
For example, if a frame has 76 rows and 181 columns, the return value

it is relative to the top edge (for positive ARG) or the bottom edge

+ * window.h (MINI_WINDOW_P): Use NILP.
+
+ * coding.h (ENCODE_SYSTEM, DECODE_SYSTEM): Define also for non-NT.
+
+ * termhooks.h (struct input_event): Use proper type for `kind'.

+
+ This handles unknown keysyms better than before. For example,
+ after `xmodmap -e 'keysym F5 = ccaron' in a Latin-1 environment,
+ Emacs formerly completely ignored F5. With the change, it derives
+ a key symbol from the name of the X keysym, `ccaron' in this case.
+ Reported by Martin Buchholz.
+
+ * xterm.c (XTread_socket): Return a non_ascii_keystroke for
+ unknown keysyms.
+
+ * keyboard.c (make_lispy_event) [HAVE_X_WINDOWS]: If we know
+ that EVENT->code isn't a function key, use the keysym's name.

+ FOREACH is a macro that should make it easier to loop over Lisp
+ lists with checks for cycles and proper lists.
+
+ * lisp.h (LIST_END_P, FOREACH): New macros.

+
+ On some systems, XtCloseDisplay seems to cause a SIGSEGV when
+ called for a lost connection. Prevent dumping core in this case.
+ Instead print the X error, and exit. On user request.
+
+ * xterm.c (error_msg): New variable.
+ (x_fatal_error_signal): New function.
+ (x_connection_closed): Set error_msg. Install x_fatal_error_signal
+ as fatal_error_signal_hook around the call to XtCloseDisplay.
+
+ * emacs.c (fatal_error_signal_hook): New variable.
+ (fatal_error_signal): Call that function.

+ With this, Emacs prints how much pure storage it will
+ approximately need in case pure storage overflows while dumping.

+ * alloc.c (purebeg, pure_size, pure_bytes_used_before_overflow):
+ New variables.
+ (init_alloc_once): Initialize new variables.
+ (PURE_POINTER_P): Use new variables.
+ (pure_alloc): If pure storage overflows, allocate from the heap.
+ (check_pure_size): New function.
+ (Fgarbage_collect): Don't GC if pure storage has overflowed.

+ * lisp.h (pure_size) [HAVE_SHM]: Declare extern size_t.

+ This adds a post-gc-hook that's run with GC inhibited.
+ Requested by Francois Pinard. XEmacs has it. Added to NEWS.

+
+ This adds `defvaralias' and `indirect-variable'. Changes not
+ directly related to this feature are there to gain the same
+ performance again as before variable aliases.
+
+ You must use the SYMBOL_VALUE and SET_SYMBOL_VALUE macros in C
+ code to get and set symbol values, to take defvaralias into account.
+
+ (Note: the new `constant' bit-flag in symbols would make it
+ possible to define arbitrary read-only variables, e.g. with
+ `defconst'.)
+
+ Documentation is in lispref/variables.texi. Added to NEWS.
+
+ * lisp.h (enum symbol_interned): New enumeration.
+ (struct Lisp_Symbol): Remove member `obarray', add
+ `indirect_variable', `constant', and `interned'.
+ (SYMBOL_INTERNED_P, SYMBOL_INTERNED_IN_INITIAL_OBARRAY_P)
+ (SYMBOL_CONSTANT_P, SYMBOL_VALUE, SET_SYMBOL_VALUE): New macros.
+ (indirect_variable): Add prototype.
+
+ * print.c (print_preprocess, print_object): Test internedness of
+ symbols differently.
+
+ * lread.c (Fintern, Funintern): Set symbol's interned and constant
+ bit-fields.
+ (init_obarray): Likewise for t and nil.
+
+ * eval.c Use SYMBOL_VALUE/SET_SYMBOL_VALUE.
+ (Fdefvaralias): New function.
+ (specbind): Simplify the test if symbol is a constant.

+ (Fmakunbound): Simplify the test if symbol is a constant.
+ (indirect_variable, Findirect_variable): New functions.
+ (swap_in_symval_forwarding): If SYMBOL is an alias, use the
+ aliased symbol.
+ (let_shadows_buffer_binding_p): Check for variable aliases.
+ (set_internal): Simplify the test if SYMBOL is a constant.
+ If SYMBOL has a buffer-local value and is an alias, use the aliased
+ symbol instead.
+ (syms_of_data): Initialize Qcyclic_variable_indirection and defsubr
+ Sindirect_variable.
+
+ * bytecode.c (Fbyte_code) <varref>: Use SYMBOL_VALUE.
+ (Fbyte_code) <varset>: Simplify the test if symbol's value can be
+ set directly.
+
+ * alloc.c (Fmake_symbol): Adapt to changes of struct Lisp_Symbol.
+
+ * abbrev.c, buffer.c, coding.c, fns.c, frame.c, keyboard.c:
+ * minibuf.c, sunfns.c, w16select.c: Use SYMBOL_VALUE/
