* doc/misc/eglot.texi (Eglot Features): Add comma after @xref.
* msdos/sed2v2.inp (GNULIB_ISSYMLINK): Define to 1.
* msdos/sedlibmk.inp (HAVE_RANDOM_H): Undefine, in line with its
deletion from gnulib.mk.
(GL_GNULIB_STRINGEQ): Define to 1.
* src/msdos.c (careadlinkat): NULL terminate at the end of the
data written, not one character beyond the same.
* 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.
* config.bat (mvOk): Protoize.
(djgppOk): Include sys/version.h for _DJGPP_MINOR.
* lisp/loadup.el: If system-type is ms-dos, dump bootstrap-emacs
as b-emacs.dmp.
* msdos/INSTALL: Document new versions of tools that have been
verified successfully to compile Emacs.
* msdos/emacs.djl: New linker script that arranges to link
symbols in `.subrs' in a contiguous part of data, as the DJGPP
runtime appears to treat any non-data and non-text section as
allocatable.
* msdos/mainmake.v2 (install): Install emacs.dmp alongside
emacs.exe.
* msdos/sed1v2.inp (CFLAGS): Define to -O2 -g3.
(LDFLAGS): Provide the said linker script.
(HAVE_PDUMPER): Define to yes.
(UNEXEC_OBJ, PAXCTL_dumped, PAXCTL_notdumped): Delete.
(DUMPING): Set to pdumper.
(MAKE_PDUMPER_FINGERPRINT): Don't erase this variable.
Don't stubify or set minstack. Remove native-comp specific
directives. Don't remove temacs prior to copying and replace
`pdmp' extension with DOS-conformant `dmp'.
* msdos/sed2v2.inp (HAVE_UNEXEC): Remove definition.
(HAVE_PDUMPER): Define to 1.
* msdos/sed6.inp (top_srcdir): Define appropriately.
* msdos/sedlibmk.inp (HAVE_BLKCNT_T): Define to 1.
* src/emacs.c (load_pdump) [MSDOS]: Use `dmp' suffix.
* src/pdumper.c (Fdump_emacs_portable) [MSDOS]: Replace ".pdmp"
suffixes with ".dmp".
With the removal of unexec and purespace, the definitions in these files
are no longer used. Remove them.
* src/firstfile.c:
* src/lastfile.c: Delete unused files.
* configure.ac (PRE_ALLOC_OBJ, POST_ALLOC_OBJ, FIRSTFILE_OBJ):
Remove variables and dependent code.
* msdos/autogen/Makefile.in:
* msdos/sed1v2.inp:
* src/Makefile.in: Don't use above deleted variables.
* src/deps.mk: Remove lastfile.c dependencies.
* config.bat: Generate stdbit.in-h from stdbit.in.h.
* msdos/sedlibmk.inp (GL_STDC_...): Enable generation
of ISO C2x features.
(STDBIT_H): Define to stdbit.h.
(GL_GENERATE_STDBIT_H_CONDITION): Define to 1.
* msdos/sedlibmk.inp (OMIT_GNULIB_MODULE_boot-time): Define to
true.
* src/filelock.c (get_boot_sec) [MSDOS]: Return 0; this
information is probably unavailable. It is also irrelevant as
MS-DOS is a single-process operating system.
* m4, lib: Update from Gnulib.
* msdos/sedlibmk.inp: Remove variables deleted as part of previous
change.
* admin/merge-gnulib (GNULIB_MODULES): Remove vasprintf and
printf-posix.
