         (w32_list_synthesized_fonts): Fix argument to alloca.

+        * 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.
+        (check_pure_size): Add prototype.
+
+        * emacs.c (Fdump_emacs_data, Fdump_emacs): Call check_pure_size.

+
+        This adds a post-gc-hook that's run with GC inhibited.
+        Requested by Francois Pinard.  XEmacs has it.  Added to NEWS.
+
+        * alloc.c (Vpost_gc_hook, Qpost_gc_hook): New variables.
+        (syms_of_alloc): DEFVAR_LISP post-gc-hook, initialize Qpost_gc_hook.
+        (Fgarbage_collect): Run post-gc-hook.
+

+
+        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.
+        (syms_of_eval): Defsubr Fdefvaralias.
+
+        * data.c: Use SYMBOL_VALUE/SET_SYMBOL_VALUE.
+        (Qcyclic_variable_indirection): New variable.
+        (Fkeywordp): Check for internedness differently.
+        (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/
+        SET_SYMBOL_VALUE macros instead of accessing symbol values directly.
