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

Set a new variable if `dbus_message_set_allow_interactive_authorization'
is available.

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.
* build-aux/ndk-build-helper-1.mk:
* build-aux/ndk-build-helper-2.mk:
* build-aux/ndk-build-helper.mk: Do not generate file names with
redundant directory separators, to port to systems where the
semantics of this are undefined.
* configure.ac: Provide a cache file to the recursive invocation
of configure if one is specified for the initial.
* cross/ndk-build/Makefile.in (my-dir): Better conform to the
original ndk-build by generating directory names with no

substitute the same if targeting SDK 8.

* java/Makefile.in (GZIP_PROG, ZIP): New substitutions.
(.PHONY): Delete references to directory-tree.

separate directories, with one for large files, another for
gzipped files, and one more for the remainder.
(install_temp/assets/directory-tree, install_temp/assets/version)
(install_temp/assets/build_info): Merge these rules into

and earlier that unserviceable functions may not be selected.
