+       * frame.c (Fmake_terminal_frame): Prefer safer CONSP over !NILP.

+       * coding.h (ENCODE_FILE, DECODE_FILE, DECODE_SYSTEM): Remove special
+       case for the special 0 coding-system.
+
+       * buffer.c (Fset_buffer_multibyte): Signal an error instead of widening.

+       Fix a malloc race condition involving strsignal.
+       A signal can arrive in the middle of a malloc, and Emacs's signal
+       handler can invoke strsignal, which can invoke malloc, which is
+       not portable.  This race condition bug makes Emacs hang on GNU/Linux.
+       Fix it by altering the signal handler so that it does not invoke
+       strsignal.
+       * emacs.c (shut_down_emacs): Use safe_strsignal, not strsignal.
+       * process.c (status_message): Use const pointer, in case strsignal
+       is #defined to safe_strsignal.
+       * sysdep.c (sys_siglist, init_signals): Always define and
+       initialize a substitute sys_siglist if the system does not define
+       one, even if HAVE_STRSIGNAL.
+       (safe_strsignal): Rename from strsignal.  Always define,
+       using sys_siglist.  Return a const pointer.
+       * syssignal.h (safe_strsignal): New decl.
+       (strsignal) [!HAVE_STRSIGNAL]: Define in terms of safe_strsignal.

+       * w32proc.c (timer_loop): Fix code that waits for timer
+       expiration, to avoid high CPU usage.

+
+       * emacs.c: Move the inclusion of TERM_HEADER after including
+       windows.h on WINDOWSNT.  This avoids compilation problems with

+       (RVA_TO_PTR): Cast the result of RVA_TO_OFFSET to 'unsigned char *',
+       as the previous version used 'void *'.
+
+       * ralloc.c (ROUNDUP): Fix last change.
+       (MEM_ROUNDUP): Don't cast MEM_ALIGN, it is already of type
+       'size_t'.

        * w32proc.c <disable_itimers>: New static flag.
