+ * s/usg5-4-common.h, src/s/unixware.h:
+ Remove define/undef of HAVE_SYSV_SIGPAUSE (not used since 2010-05-04).
+
+ * s/gnu.h (POSIX_SIGNALS): Remove (not used since 2010-05-04).

+
+ USE_LISP_UNION_TYPE + USE_LSB_TAG cleanup (Bug#11604)
+ * alloc.c (make_number) [!defined make_number]:
+ Remove, as lisp.h always defines this now.
+ (mark_maybe_pointer): Simplify since USE_LSB_TAG is always defined now.
+ (roundup_size): Verify that it is a power of 2.
+ * data.c (Fmake_variable_buffer_local, Fmake_local_variable):
+ * ftfont.c (ftfont_driver): Use LISP_INITIALLY_ZERO.
+ * lisp.h (USE_LSB_TAG): Allow the builder to compile with
+ -DUSE_LSB_TAG=0, to override the automatically-selected default.
+ USE_LSB_TAG now is always defined to be either 0 or 1.
+ All uses changed.
+ (union Lisp_Object): Don't worry about WORDS_BIGENDIAN; the
+ code works fine either way, and efficiency is not a concern here,
+ as the union type is for debugging, not for production.
+ (LISP_MAKE_RVALUE, make_number) [USE_LISP_UNION_TYPE]:
+ Use an inline function on all platforms when using the union type,
+ since this is simpler and 'static inline' can be used portably
+ within Emacs now.
+ (LISP_INITIALLY_ZERO): New macro.
+ (XFASTINT, XSETFASTINT) [USE_LISP_UNION_TYPE]: Remove.
+ (XSET) [USE_LISP_UNION_TYPE]: Don't overparenthesize.
+
