I have been using this change for many months in my private copy
of Emacs, and have used it to find several bugs.  It's mature
enough to publish now.
* Makefile.in (GNULIB_MODULES): Add warnings, manywarnings.
* configure.in: Support --enable-gcc-warnings, in the style of
other GNU packages such as coreutils.
(C_WARNINGS_SWITCH): Remove, replacing with...
(WARN_CFLAGS, GNULIB_WARN_CFLAGS): New variable.
(PKG_CHECK_MODULES, C_SWITCH_X_SITE): Use -isystem rather than -I,
when including system files with GCC.
* etc/NEWS: Mention --enable-gcc-warnings.
* lib/Makefile.am (AM_CFLAGS): New macro.
* m4/manywarnings.m4, m4/warnings.m4: New files, from gnulib.
* lib-src/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(BASE_CFLAGS): Use new macros rather than old.
* lwlib/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* oldXMenu/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* src/Makefile.in (C_WARNINGS_SWITCH): Remove.
(WARN_CFLAGS, WERROR_CFLAGS): New macros.
(ALL_CFLAGS): Use new macros rather than old.
* src/process.c: Ignore -Wstrict-overflow to work around GCC bug 52904.
* src/regex.c: Ignore -Wstrict-overflow.  If !emacs, also ignore
-Wunused-but-set-variable, -Wunused-function, -Wunused-macros,
-Wunused-result, -Wunused-variable.  This should go away once
the Emacs and Gnulib regex code is merged.
(xmalloc, xrealloc): Now static.

* composite.c (get_composition_id): Use 'double' consistently
instead of converting 'float' to 'double' and vice versa; this is
easier to understand and avoids a GCC warning.

* src/Makefile.in: (leimdir): New variable.
($(leimdir)/leim-list.el): New rule.
(emacs$(EXEEXT)): Depend on leim-list.el.

Fixes: debbugs:4789

* Makefile.in (leim): Check cd return value.  Pass fewer variables.
(install-leim): Check cd return value.  Pass $MFLAGS.
(install-strip): Pass $MFLAGS.

* leim/Makefile.in: (TIT_GB, TIT_BIG5, CHINESE_TIT, MISC, TIT_MISC):
Make them store the .el files rather than the .elc files.
(NON_TIT_GB, NON_TIT_BIG5, CHINESE_NON_TIT, CHINESE_GB)
(CHINESE_GB, CHINESE_BIG5, JAPANESE, KOREAN, THAI, VIETNAMESE)
(LAO, INDIAN, TIBETAN, LATIN, UNICODE, SLAVIC, GREEK, RUSSIAN)
(OTHERS, CHINESE, EASTASIA, ASIA, EUROPEAN, WORLD, NON_TIT_MISC):
Remove variables listing the non-generated .el files.
(.el.elc): Add explicit load-path for quail.
(all): Depend on compile-main rule rather than $WORLD.
(changed.tit, changed.misc): Also depend on $SUBDIRS.
(leim-list.el): Don't depend on changed.tit or changed.misc.
Remove unnecessary compilation check.
(setwins, compile-targets, compile-main): New.
(clean, mostlyclean): Update for change in TIT_MISC contents.
(bootstrap-clean): Use a glob match to delete .elc, not a fixed list.

(latin-ltx--ascii-p): New function.
(latin-ltx--define-rules): New macro.
(define-rules): Use it.

This function was removed with ucs-tables.el in 2008.

* lisp/international/mule-cmds.el (set-default-coding-systems):
* lisp/files.el (normal-mode):
Remove guarded calls to ucs-set-table-for-input. 

* src/buffer.c (Qucs_set_table_for_input): Remove.
(Fget_buffer_create): Don't call Qucs_set_table_for_input.
(init_buffer_once, syms_of_buffer): Remove Qucs_set_table_for_input.

Eg org.texi has been using 4.7 functions for some time.

proper alignment.

 lisp/textmodes/ispell.el (ispell-check-version): For hunspell, set
 ispell-encoding8-command to "-i", without a trailing space.
 (ispell-start-process): For hunspell, use '("-i" ENCODING), in 2
 separate command-line arguments, to specify the encoding, since
 that's how hunspell expects it.

This reduces somewhat the number of "rogue" settings in emacs -Q.

* configure.in (PKG_CHECK_MODULES): Do not assume that pkg-config
works; check its exit status.  Problem reported by Jordi Gutiérrez
Hermoso in

Fixes: debbugs:8054

* alloc.c (POINTERS_MIGHT_HIDE_IN_OBJECTS): New macro.
(mark_memory): Mark Lisp_Objects only if pointers might hide in
objects, as mark_maybe_pointer will catch them otherwise.
(GC_LISP_OBJECT_ALIGNMENT): Remove; no longer needed.
* s/gnu-linux.h (GC_LISP_OBJECT_ALIGNMENT) [__mc68000__]: Likewise.

* xml.c (libxml2_loaded_p) [!!WINDOWSNT]: 'inine' -> 'inline'.

 (all-other-dirs-$(MAKETYPE)): Depend on maybe-bootstrap.

 src/character.h (STRING_CHAR, STRING_CHAR_AND_LENGTH): Add comments
 about subtle differences between FETCH_CHAR* and STRING_CHAR*
 macros related to unification of CJK characters.  For the details,
