Also, update description of debuginfo and sources to match
Debian and Red Hat more accurately, and move this sad tale
from INSTALL to etc/PROBLEMS which is a better home for it.
* Makefile.in (emacs_srcdir, install-c-src):
* configure.ac (emacs_srcdir, --with-install-srcdir):
* src/epaths.in (PATH_EMACS_SOURCE):
* src/lread.c (emacs-source-directory):
Remove. All uses removed.
* lisp/emacs-lisp/find-func.el (find-function-C-source):
Do not worry about compressed C sources.
* src/lread.c: Do not include <dosname.h>.
Without this change, on typical GNU/Linux distributions
like Debian, the first button of ‘C-h f car RET’ does not work
because the source code for ‘car’ is not installed (Bug#37527).
Fix this by installing the (compressed) C source code alongside
the (compressed) Lisp source code that is already installed.
This adds about 3 MB (about 2%) to the size of the installed files
on my platform.
* Makefile.in (emacs_srcdir): New macro.
(epaths-force): Substitute PATH_EMACS_SOURCE.
(install-c-src): New rule, that installs a copy of the C source
code if emacs_srcdir says to.
(install-arch-indep): Depend on it.
* configure.ac (emacs_srcdir): New var.
Add support for --disable-install-srcdir.
* lisp/emacs-lisp/find-func.el (find-function-C-source-directory):
Look in emacs-source-directory first.
(find-function-C-source): Also look for gzipped source files.
* lisp/startup.el (normal-top-level):
Also recode emacs-source-directory.
* src/epaths.in (PATH_EMACS_SOURCE): New macro.
* src/lread.c: Include dosname.h, for IS_ABSOLUTE_FILE_NAME.
(syms_of_lread): New var emacs-source-directory.
It’s not needed, since Emacs always uses the system putenv and all
platforms have putenv. This improves on the fix for Bug#19874.
Suggested by Bruno Haible.
* admin/merge-gnulib (GNULIB_MODULES): Remove putenv.
* configure.ac: Remove workarounds for Gnulib putenv module.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.
* lib/putenv.c, m4/putenv.m4: Remove.
Rewrite an ancient Alpha ELF check to port to a future Gnulib
version that may require AC_CHECK_DECL to be set up properly as
per the ‘Expanded Before Required’ section of the Autoconf manual
Autoconf doesn’t guarantee that AC_CHECK_DECL will work properly
if called conditionally (e.g., inside a shell ‘case’ statement)
and the condition is false. Problem reported by Bruno Haible in:
https://lists.gnu.org/r/bug-gnulib/2020-01/msg00088.html
* configure.ac (LD_SWITCH_MACHINE): Migrate ELF check later,
when AC_CHECK_DECL is properly set up.

On macOS, shared libraries typically have the suffix .dylib. This
commit switches the module suffix to .dylib on Darwin to account for
that. To also support the .so suffix, introduce the concept of a
secondary module suffix.
* configure.ac: Switch MODULES_SUFFIX to .dylib for Darwin, introduce
MODULES_SECONDARY_SUFFIX.
* src/lread.c (Fload, syms_of_lread): Also use
MODULES_SECONDARY_SUFFIX if defined.
* test/src/emacs-module-tests.el (module-darwin-secondary-suffix): New
unit test.
* configure.ac: Substitute environment function snippet for Emacs 28.

* configure.ac (HAVE_HARFBUZZ): Remove the check for explicit
harfbuzz -- have_harfbuzz defaults to "yes", so we have no way of
checking whether the user really asked for it, apparently.
Problem reported by Richard Copley (Bug#37852).
This patch causes the problem to not occur if one uses plain
‘configure’. The problem can still occur if with ‘configure
--enable-gcc-warnings’, so a further fix may be needed.
* configure.ac (GNULIB_PORTCHECK, _FORTIFY_SOURCE):
Define these only with an explicit --enable-gcc-warnings.
With --enable-checking, make_fixnum (N) now checks that N is
in fixnum range. Suggested by Pip Cet in:
https://lists.gnu.org/r/emacs-devel/2019-07/msg00548.html
A new function make_ufixnum (N) is for the rare cases where N
is intended to be unsigned and is in the range 0..INTMASK.
* configure.ac (AC_C_TYPEOF): Add.
(HAVE_STATEMENT_EXPRESSIONS): Resurrect this macro.
* src/fns.c (Frandom, hashfn_eq, hashfn_equal, hashfn_user_defined):
* src/profiler.c (hashfn_profiler):
Use make_ufixnum rather than make_fixum, since the argument is
an unsigned integer in the range 0..INTMASK rather than a signed
integer in the range MOST_NEGATIVE_FIXNUM..MOST_POSITIVE_FIXNUM.
Typically this is for hashes.
* src/lisp.h (lisp_h_make_fixnum_wrap) [USE_LSB_TAG]:
Rename from lisp_h_make_fixnum.
(lisp_h_make_fixnum): Redefine in terms of lisp_h_make_fixnum_wrap.
Check for fixnum overflow on compilers like GCC that
have statement expressions and typeof.
(FIXNUM_OVERFLOW_P): Move up.
(make_fixnum): Check for fixnum overflow.
(make_ufixnum): New function, which checks that the arg
fits into 0..INTMASK range.
Suggested by Paul Eggert (Bug#36405#22).
* configure.ac (HAVE_CYGWIN_O_PATH_BUG): New AC_DEFINE, for Cygwin
versions 3.0.0 through 3.0.7.
* src/dired.c (O_PATH) [__CYGWIN__]: Remove #undef.
(file_attributes) [HAVE_CYGWIN_O_PATH_BUG]: Don't use O_PATH.
* admin/unidata/Makefile.in (maintainer-clean):

(x_begin_cr_clip) [USE_CAIRO]: Use it.
(xlib_surface_key, saved_drawable_key) [USE_CAIRO]: New variables.
(x_cr_destroy_xlib_surface, x_try_cr_xlib_drawable)
(x_end_cr_xlib_drawable) [USE_CAIRO]: New functions.
(x_draw_composite_glyph_string_foreground)
(x_draw_glyph_string_foreground) [USE_CAIRO]: Get Xlib surface when drawing
text with X core fonts into bitmap surfaces. Add fallback code for drawing
into outline surfaces.
* src/hbfont.c: New file, with code moved from w32uniscribe.c
and renamed/modified as appropriate.
* src/w32uniscribe.c: Move to hbfont.c DEF_DLL_FN and macro
definitions for HarfBuzz functions used in hbfont.c
(load_harfbuzz_funcs): Move loading of HarfBuzz functions used
by hbfont.c to hbfont.c:hbfont_init_w32_funcs, and call that
function from here.
(syms_of_w32uniscribe_for_pdumper): Fill the 'shape' and

[HAVE_HARFBUZZ]: Define typedefs for HarfBuzz functions to be
loaded dynamically from the HarfBuzz DLL. Define macros to
call those functions via function pointers.
(uniscribe_open) [HAVE_HARFBUZZ]: Use the HarfBuzz font driver

(uniscribe_close) [HAVE_HARFBUZZ]: For fonts using the
HarfBuzz backend, call hb_font_destroy to free memory used for

* doc/emacs/msdos.texi (Windows Fonts): Document support for
HarfBuzz text shaping on MS-Windows.
* configure.ac (HAVE_HARFBUZZ): Move out of the X-specific
part, and consider HarfBuzz also for HAVE_W32 systems.
Require HarfBuzz v1.2.3 for w32.
* INSTALL, INSTALL.REPO, admin/make-tarball.txt:
Mention ‘make check’.
* configure.ac: Update comment.
* etc/NEWS: Say that tarballs have a test directory.
* make-dist (with_tests): Default to "yes".
Add an option --no-tests to make it "no".
ImageMagick has continuing stability and security problems, suggesting
that 'configure' should disable it by default. See Glenn Morris's notes
at: https://lists.gnu.org/r/emacs-devel/2018-12/msg00036.html
* INSTALL, etc/NEWS, nt/INSTALL.W64: Mention this.
* configure.ac (imagemagick): Default to off.
* Makefile.in (top_distclean): Clean makefile as well as Makefile.
* configure.ac: If not using plain ‘make’, create a makefile
so that plain ‘make’ simply calls $(MAKE).
It doesn’t work anymore, and these days ‘gcc -fsanitize=address’
does a better job anyway.
* configure.ac: Remove the option.
* configure.ac (ac_xmalloc_overrun, XMALLOC_OVERRUN_CHECK):
* src/alloc.c (XMALLOC_OVERRUN_CHECK_OVERHEAD)
(XMALLOC_OVERRUN_CHECK_SIZE, XMALLOC_OVERRUN_SIZE_SIZE)
(xmalloc_overrun_check_header, xmalloc_overrun_check_trailer)
(xmalloc_put_size, xmalloc_get_size, overrun_check_malloc)
(overrun_check_realloc, overrun_check_free):

* etc/NEWS: Mention this.
* configure.ac: Use EMACS_CHECK_MODULES fors LCMS2 rather than
AC_SEARCH_LIBS.
* src/Makefile.in: Get LCMS2_LIBS and LCMS2_CFLAGS from configure,
instead of just LIBLCMS2.
(cherry picked from commit cb3863370c)
* configure.ac: Bump required GTK 2 and GTK 3 versions and the
associated GLib versions. Remove obsolete AC_CHECK_FUNCS calls. These
check for functions available in later GTK 2 versions. These checks
and can safely be removed with the exception of
gtk_window_set_has_resize_grip, which according to a comment in
gtkutil.c causes an issue in Ubuntu's GTK 2.
* src/gtkutil.c:
* src/xfns.c:
* src/xterm.c:
* src/xterm.h: Remove now unused conditional blocks. Use HAVE_GTK3
instead of GTK_CHECK_VERSION where now applicable. Remove checks of

* admin/merge-gnulib (GNULIB_MODULES): Add memmem-simple.
(AVOIDED_MODULES): Add memchr.

fingerprint.h, intprops.h, min-max.h.
(SSIZE_MAX): New macro, if not already defined.

instead of generating a fingerprint.c.
* lib/Makefile.in (libgnu_a_OBJECTS): Add fingerprint.o.
* lib/gnulib.mk.in, m4/gnulib-comp.m4: Regenerate.

Bring back the dmpstruct.h checking, and use it when
--enable-checking=structs is specified. The checking can be helpful

* lib-src/emacsclient.c: Simplify by assuming HAVE_SOCKETS and
HAVE_INET_SOCKETS, which are always true nowadays, except perhaps
for MS-DOS and if so this program shouldn’t be built there anyway.
Don’t bother including sys/types.h, as it’s not needed on modern
systems (and syswait.h does it for us anyway).
(main): Simplify by assuming SIGSTOP (which is always defined
if SIGCONT is), and by assuming HAVE_SOCKETS && HAVE_INET_SOCKETS.
Problem reported by Joseph Mingrone in:
https://lists.gnu.org/r/emacs-devel/2018-10/msg00238.html
While we’re at it, apply a similar fix to struct Lisp_Subr; this
removes the need for GCALIGNED_STRUCT_MEMBER and thus can shrink
struct Lisp_Subr a bit.
* configure.ac (HAVE_STRUCT_ATTRIBUTE_ALIGNED): Bring back this macro.
Although used only for performance (not to actually align
structures), we might as well take advantage of it.
* src/lisp.h (GCALIGNED_STRUCT_MEMBER): Remove; all uses removed.
(union Aligned_Lisp_Subr): New type, like struct Lisp_Subr but aligned.
* src/lisp.h (XSUBR, DEFUN):
* src/lread.c (defsubr): Use it. All callers changed.

(main_thread): Now of this type, so it’s aligned.
All uses changed.
* src/xmenu.c (syms_of_xmenu) [USE_GTK || USE_X_TOOLKIT]:
Adjust to union Aligned_Lisp_Subr change.
Without this patch, Emacs dumps core on Fedora 28 x86-64
when configured via "CC='gcc -m32' --enable-gcc-warnings
--without-imagemagick --without-gif --with-modules
PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig:/usr/share/pkgconfig".
and then when run normally in a windowing system.
'make check' and 'emacs -nw' work OK even without the patch.
* configure.ac (LD_SWITCH_SYSTEM_TEMACS): Prepend
-znocombreloc if supported and if dumping. This mostly
reverts 2018-06-15T21:37:39!eggert@cs.ucla.edu "Remove old
combreloc hack".

d2ad4ba Do not consider external packages to be removable (Bug#27822)
ec0995c * src/alloc.c: Remove obsolete comments.
ec6f588 Better support utf-8-with-signature and utf-8-hfs in HTML
eb026a8 Don't use -Wabi compiler option
* configure.ac (GMP_OBJ): When building mini-gmp, compile
mini-gmp-emacs.c, not mini-gmp.c.
* lib-src/etags.c (NDEBUG): Don't attempt to redefine, in
case the builder compiles with -DNDEBUG.
* src/conf_post.h (NDEBUG) [!ENABLE_CHECKING && !NDEBUG]: Define.
This avoids bloat in mini-gmp-emacs.o.

IEEE_FLOATING_POINT, not if HAVE_IEEE754_H.
* src/lread.c (string_to_number):
* src/print.c (float_to_string):
Process NaNs only on IEEE hosts, and assume <ieee754.h>
in that case.
Mostly, this avoids munging executables when CANNOT_DUMP = yes,
as the munging is needed only for unexec.
* configure.ac (PAXCTL_dumped, PAXCTL_notdumped) [CANNOT_DUMP]:
Leave these empty.
(LD_SWITCH_SYSTEM_TEMACS) [CANNOT_DUMP]:
Do not append -no-pie or -nopie.
* src/alloc.c (my_heap_start) [CANNOT_DUMP]: Omit; not used.
It has not been needed for many years and gets in the way of
portable dumping, address sanitization, etc. See:
https://lists.gnu.org/r/emacs-devel/2016-12/msg00147.html
* configure.ac (LDFLAGS_NOCOMBRELOC, emacs_cv_znocombreloc):
Remove. All uses removed.

Add a decl with UNINIT to work around GCC bug 85563.
* src/menu.h (finish_menu_items):
Do not use attribute const.
* src/regex.c (analyze_first): Use FALLTHROUGH, not a comment.
* configure.ac: Use EMACS_CHECK_MODULES fors LCMS2 rather than
AC_SEARCH_LIBS.
* src/Makefile.in: Get LCMS2_LIBS and LCMS2_CFLAGS from configure,
instead of just LIBLCMS2.
* configure.ac: Use the Carbon framework on macOS.
* src/nsterm.m (ns_get_shifted_character) [NS_IMPL_COCOA]: New function.
(EmacsView::keyDown) [NS_IMPL_COCOA]: Use ns_get_shifted_character
when we have shift style modifiers.
Problem reported by Werner Lemberg in:
https://lists.gnu.org/r/emacs-devel/2018-02/msg00304.html
with a further fix suggested by Glenn Morris in Bug#30431#14.
* configure.ac: Try pkg-config before libpng-config.
Adjust LIBPNG accordingly, and append -lz regardless of
whether it was pkg-config.
