* configure.ac (systemduserunitdir): New variable and option.
* Makefile.in (systemduserunitdir): New, set by configure.
(install-etc, uninstall): Don't install emacs.service when
systemduserunitdir is unspecified.
* etc/NEWS: Announce the new configure option. (Bug#76924)
* configure.ac: Don't claim that Xft is being considered for
deletion or that recent releases are buggy, or imply that
HarfBuzz support is exclusive to Cairo.
* configure.ac (ALIGNOF_INT, ALIGNOF_LONG, ALIGNOF_LONG_LONG):
New variables.
(emacs_cv_alignas_unavailable): Define if alignas and structure
alignment primitives are unavailable. In such an environment,
the MSB tagging scheme must be enabled, as must the GNU malloc.
* msdos/sed2v2.inp: Adjust correspondingly.
* src/alloc.c (union emacs_align_type): Remove types which
contain flexible array members. The address of a field
subsequent to an aggregate with flexible array members cannot
validly be taken.
(mark_memory) [!USE_LSB_TAG && !WIDE_EMACS_INT]: Strip type bits
before scanning memory.
* src/emacs.c (main):
* src/eval.c (Fautoload_do_load):
* src/fns.c (Frequire): Rename a number of illogically named
fields.
* src/lisp.h (ALIGNOF_EMACS_INT): Define to the natural
alignment of EMACS_INT.
(IDEAL_GCALIGNMENT): New macro.
(USE_LSB_TAG): Disable if no alignment specifiers are available,
WIDE_EMACS_INT is undefined, and the natural alignment of
EMACS_INT falls short of LSB tagging's requirements.
(gflags): Rename illogically named fields and don't define them
as bitfields, which runs afoul of certain compiler issues.
(will_dump_p, will_bootstrap_p, will_dump_with_pdumper_p)
(dumped_with_pdumper_p): Adjust accordingly.
* src/pdumper.c (VM_SUPPORTED): Define to 0 when !USE_LSB_TAG.
It is better to read dump files into the heap by hand than to be
supplied with an address that is not representable.
(_dump_object_start_pseudovector): Rename to
dump_object_start_pseudovector, to avoid encroaching on reserved
names.
(START_DUMP_PVEC): Adjust correspondingly.
(dump_mmap_contiguous_vm): Preserve errno around failure
cleanup.
(dump_bitset_bit_set_p): Work around certain compiler issues.
(pdumper_load) [!USE_LSB_TAG]: Reject dump file allocations
that are not representable as Lisp_Objects.
Tested on i386-unknown-solaris2.10, sparc-sun-solaris2.10.
1. Prefer "native-compiled" to "native compiled".
The adjective "native-compiled" with the hyphen is generally more
consistent with the typical pattern in English, especially when the
compound modifies a noun (e.g., "native-compiled code").
2. Prefer "natively compiled" to "natively-compiled".
The adverb "natively" modifies "compiled", and it is standard not
to hyphenate an adverb + adjective combination when the adverb ends
in -ly (e.g., "code that is natively compiled").
For example, note that we say "high-speed internet" but "highly
performant code".

Recent Gnulib should work around the Android NDK 16
MB_CUR_MAX bug, so Emacs no longer needs to worry about it.
* configure.ac (gl_STDLIB_H):
Remove, to stop overriding Gnulib.
* configure.ac (__ctype_get_mb_cur_max)
(emacs_cv_broken_mb_cur_max, REPLACEMENT_MB_CUR_MAX):
* src/conf_post.h (MB_CUR_MAX):
Remove, as Gnulib does this now.
This check was added to 'malloc_initialize_hook' in order to "insulate
Emacs better from configuration screwups" (commit b4788b9394). With
unexec gone, we no longer use 'malloc_set_state', and thus don't need
this check.
Note that this patch removes the last uses of the deprecated glibc
functions 'malloc_set_state' and 'malloc_get_state' from our code.
* src/alloc.c (malloc_initialize_hook) [DOUG_LEA_MALLOC]:
Remove check for working 'malloc_set_state'.
(alloc_unexec_pre) [DOUG_LEA_MALLOC]: Delete unused function.
(alloc_unexec_post) [DOUG_LEA_MALLOC]: Delete function.
(malloc_state_ptr) [DOUG_LEA_MALLOC]: Delete variable.
* configure.ac (emacs_cv_var_doug_lea_malloc): Don't check for
malloc_set_state and malloc_get_state.
This adds support for color fonts.
* configure.ac: Add src/w32drite to W32_OBJ.
* src/w32dwrite.c: New file.
(w32-initialize-direct-write): New function, initialize the
DirectWrite library if it is available, and required global
variables.
(w32_use_direct_write): New function, check if DirectWrite
is available and activated by the user.
(w32_dwrite_encode_char): New function, replacement for HarfBuzz's
'encode_char'.
(w32_dwrite_text_extents): New function, replacement for w32font
text_extents.
(w32_dwrite_draw): New function, replacement for w32font draw.
(w32_dwrite_free_cached_face): New function, used in the font
deletion process to also delete DirectWrite data.
(verify_hr): New function, verify COM method results.
(release_com): New function, release a COM object.
(w32-dwrite-available): New function, returns true if DirectWrite
is available.
(w32-dwrite-reinit): New function, reinitialize DirectWrite,
optionally setting some rendering parameters.
* src/w32font.c (w32font_text_extents): If DirectWrite is enabled,
call 'w32_dwrite_text_extents'.
(w32font_draw): If DirectWrite is enabled, call 'w32_dwrite_draw'.
* src/w32uniscribe.c: (w32hb_encode_char): If DirectWrite is enabled,
call 'w32_dwrite_encode_char'.
(syms_of_w32uniscribe_for_pdumper): Initialize DirectWrite.
(uniscribe_close): Free DirectWrite data for the font.
Bug#73730
Before this fix, it would fail to build with gcc-14 with the error:
conftest.c: In function 'main':
conftest.c:265:11: error: implicit declaration of function 'ioctl'
[-Wimplicit-function-declaration]
265 | int foo = ioctl (0, FIONREAD, &foo);
| ^~~~~
Solaris documents ioctl() as being defined in <unistd.h>.
* configure.ac: Fix FIONREAD check with gcc-14 on Solaris.

Enable GC_REMEMBER_LAST_MARKED by default (it was disabled in Emacs 29)
to make it easier to debug difficult-to-reproduce GC problems
encountered by users. This increases GC costs by about 5 %, which can
be avoided by turning the mark trace buffer back off using the new
--disable-gc-mark-trace option.
See discussion at
https://lists.gnu.org/archive/html/emacs-devel/2024-09/msg00240.html
* configure.ac (--disable-gc-mark-trace): New config option.
* etc/NEWS: Mention it.
* src/alloc.c: Enable it by default and avoid a compiler warning.
* configure.ac: Temporary workaround for Gnulib bug. Verify
that the provided android.jar corresponds to Android 35, or any
later version.
* cross/ndk-build/Makefile.in (NDK_BUILD_SO_LDFLAGS): New
variable.
* cross/ndk-build/ndk-resolve.mk
(NDK_LOCAL_A_NAMES_$(LOCAL_MODULE)): Define to
NDK_BUILD_SO_LDFLAGS by default to enable building binaries
with support for 16 kb page sizes.
* java/AndroidManifest.xml.in: Target SDK 35.
* java/INSTALL (16KB PAGE SIZES): New section. Replace
references to Android 34 with 35.
* java/org/gnu/emacs/EmacsActivity.java (onCreate): Restore
pre-SDK 35 inset-relative placement.
* java/org/gnu/emacs/EmacsFillPolygon.java (perform): Suppress
deprecation warnings, and document why.
* m4/ndk-build.m4 (ndk_INIT, ndk_LATE): Check for and enable
toolchain support for 16 KB page sizes, if available.
(ndk_CONFIG_FILES): Export linker options so derived.
* src/conf_post.h [__ANDROID_API__ < 35]: Include system time.h
and redefine timezone_t to rpl_timezone_t, so that the Gnulib
replacement may not conflict with the useless OS type.
* configure.ac (emacs_cv_gcc_bug_58416_CFLAGS):
No need for a workaround in GCC 15.
2024-08-19 Paul Eggert <eggert@cs.ucla.edu>
Remove obsolete comment about ‘volatile’
* configure.ac (C_SWITCH_MATCHINE): On 32-bit x86 with GCC 4+,
append -mfpmath=sse (if SSE2 is known to work) or -fno-tree-sra
(otherwise) to work around GCC bug 58416.
* etc/NEWS: Mention this.
* configure.ac: Go back to preferring -isystem to -I,
as headers like <gobject/gparam.h> still need it. This
reverts almost all of 2024-07-16T02:25:44!eggert@cs.ucla.edu,
except that the ‘nw="$nw -Wsystem-headers"’ line continues to
be removed as it is no longer needed due to recent Gnulib changes.
Problem reported by Eli Zaretskii in:
https://lists.gnu.org/r/emacs-devel/2024-07/msg00756.html
* Makefile.in (install-eln), configure.ac (emacs_cv_find_delete):
* make-dist: Use ‘find ... -exec CMD {} +’ rather than ‘find
... -exec CMD {} \;’ so that if CMD fails, ‘find’ fails too.
* Makefile.in (install-eln): Port to ‘find’ implementations that
behave differently from GNU ‘find’ when given an argument
that contains ‘{}’ within a longer string. POSIX allows
this behavior.
* configure.ac: Simplify configuration by using -I instead of
-isystem, as -isystem is no longer helpful for suppressing
diagnostics (and likely has not been helpful for years).
Do not suppress -Wsystem-headers, as Gnulib no longer enables it.
The workaround for the Android 5.0 (API 21) strnlen bug
is now done in m4/strnlen.m4, taken from Gnulib, so
there is no need for Emacs to have its own workaround.
* configure.ac (ORIGINAL_AC_FUNC_STRNLEN, AC_FUNC_STRNLEN):
Remove.
When invoking D-Bus methods, let the user enable interactive
authorization by passing an :authorizable t parameter. This makes
it possible to D-Bus methods that require polkit authorization.
* configure.ac (HAVE_DBUS_MESSAGE_SET_ALLOW_INTERACTIVE_AUTHORIZATION):
Set a new variable if `dbus_message_set_allow_interactive_authorization'
is available.
* src/dbusbind.c (dbus-message-internal): Allow interactive
authorization by passing :authorizable t.
* doc/misc/dbus.texi (Synchronous Methods, Asynchronous Methods):
* etc/NEWS:
* lisp/net/dbus.el (dbus-call-method-asynchronously): Document the
new parameter.
* configure.ac (AC_FUNC_STRNLEN): Detect a bug where strnlen is
liable to integer overflows if addition of the search limit to
the string would also overflow.
* src/xdisp.c (store_mode_line_string): Remove stopgap measure.
