+ maint: update bootstrap, (re-)enable po file generation
+ In commit 4694c4e67, I disabled bootstrap pulling in po files, because
+ I got an error while attempting to get them, and remembered that while
+ the experimental 2.0 has a .pot file, branch-1.4 (and the 1.4.18
+ release) historically did not. Basically, since the translation
+ project does not have any m4.pot corresponding to a released m4 that
+ needs it, they deleted tp/latest/m4, and with nothing to pull from,
+ rsync fails. I did not, however, realize that commit 610290de had
+ intentionally added translation support, such that m4 1.4.19 WILL have
+ translations; so until I get that directory reinstated by releasing
+ 1.4.18b, I'll just use './bootstrap --skip-po'.
+
+ Meanwhile, Gary's upstream bootstrap has had some commits
+ (https://github.com/gnulib-modules/bootstrap.git)
+ Regenerate them via:
+ for f in gl/build-aux/*; do cp ~/bootstrap/build-aux/$(basename $f) $f; done
+ gl/build-aux/inline-source gl/build-aux/bootstrap.in > bootstrap
+
+ * gl/build-aux/*: Sync from upstream.
+ * bootstrap: Regenerate.
+ * bootstrap.conf (m4_bootstrap_options_prep): Re-enable po.

+ It is faster to do an integer compare than a string compare when
+ managing hash table collisions (reserving a string compare for ties).
+ Testing with CFLAGS=-DDEBUG_SYM=1 and 'time M4=src/m4 autoconf -f',
+ the results are noticeable; on my machine, execution speeds up from

+
+ m4: lookup mode 0 called 1243301 times, 7859589 compares, 6734330 misses, 23941043 bytes

+ LIB_GETRANDOM, LIB_HARD_LOCALE, LIB_POSIX_SPAWN,
+ LIB_SETLOCALE_NULL, LIBUNISTRING, INTL_MACOSX_LIBS.
+ These are all needed by current Gnulib, according to gnulib-tool.
+ LIB_CLOCK_GETTIME is certainly needed for Solaris 10; otherwise
+ the m4 link fails with clock_gettime not found.
+
+ maint: port to macOS 11.2.3 (arm64)
+ * m4/gnulib-cache.m4: Add fopen-gnu, replacing cloexec and fopen.
+ Avoid getopt-posix-tests, since they are not needed for m4
+ and currently fail on macOS 11.2.3 (arm64).
+ * src/builtin.c (m4_incr, m4_decr): Avoid undefined behavior
+ on integer overflow that causes tests to fail on macOS.
+ * src/debug.c (debug_set_output):
+ * src/output.c (m4_tmpfile, m4_tmpopen):
+ * src/path.c (m4_fopen):
+ Use GNU fopen with "e" rather than set_cloexec_flag. This is
+ simpler, and works around a Gnulib bug on macOS with fopen
+ being replaced by rpl_fopen sometimes but not other times.
+ * src/freeze.c (produce_frozen_state): Use GNU fopen with "e";
+ no need to expose the fd to subprocesses.
+
+ build: update gnulib submodule to latest

+ symtab: drop redundant symbol flag
+ In writing the previous patch, I noticed that the shadow flag is only
+ ever set when a pushdef stack is present, which makes it redundant now
+ that the pushdef stack is separate from the hash collision stack.
+
+ * src/m4.h (SYMBOL_SHADOWED): Delete.
+ * src/builtin.c (dump_symbol): Simplify, now that hack_all_symbols
+ no longer visits shadowed macros.
+ * src/symtab.c (lookup_symbol, symtab_print_list): Simplify.

+
+ symtab: better handling of macro stacks
+ I ran into a scenario where running a program took 22s with the
+ default -H509, but less than a second with -H517 [1]. The culprit? A
+ collision between 'stack' and 'substr' in the default hash table size
+ caused lookups for substr to get progressively slower as pushdef stack
+ got deeper. This is easy enough to fix, and may also make it easier
+ to dynamically grow the hashtable.

- Changes needed to automate the release process for 1.4.3:
+ maint: bump copyright year
+ Needed to keep 'make syntax-check' passing.
- * Makefile.in (dist): Make .tar.bz2 tarball too.
- * Makefile.maint (TSDEPS_DIST): Remove m4/libtool.m4.
- (cvs-news): Look 1 line further down for NEWS release number.
- (cvs-dist): We don't use automake, so make dist is fine.
- Remove double . before suffixes.
- (cvs-release): Don't mention manual.html.
- (fetch): Get latest gendocs files.
- (web-manual): Rewritten to use gendoc for multiformat manuals.
- * doc/gendocs.sh: Don't save an old version in m4 CVS!
- * doc/m4.texinfo (Index): HFS+ (the file system on my Mac) is case
- preserving, but case insensitive, so generating html docs per node
- clashes between Index.html, the node file, and index.html, the
- top-level of the document tree...
- (Index macro): ...so renamed to this. Changed all references.

+ maint: generate ChangeLog from git commits
+ Follow the practice set in numerous other GNU projects, where
+ the ChangeLog (since 2015) is generated from git commit messages.
+ This avoids duplication or subtle differences between the two,
+ as well as making it easier to merge patches across branches
+ (as good as Bruno Haible's 'git-merge-changelog' helper program

-
- * m4.c: Complete prototype for forwarded declaration of usage.

-
- * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
- following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES

- * input.c: Use user_word_regexp if specified, instead of
- DEFAULT_WORD_REGEXP.
-
- * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to
- agree with it.
-
- * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o.

- that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and
- also tested it on a Sun Sparc workstation running SunOS 4.x.
-
- * format.c (format): When not HAVE_EFGCVT, m4 was failing the

- without selecting the proper field. Now, save the formatting type
- first, delaying the fetch of the corresponding argument.
- Reported by Joseph E. Sacco and Tom Quinn.
-
- * format.c (format): Remove const from char *fmt declaration when

-
- * builtin.c (m4_eval): Cast strlen to (int) before comparing.

- * Release 1.0.3
- This is still a beta release for the future GNU m4 version 1.1.
-
- * lib/alloca.c: New, from elsewhere.
- * lib/Makefile.in: Distribute it. Define and use $(ALLOCA).
-
- * m4.h: Do not define index/rindex if already defined. If
- FALSE/TRUE are already defined, do not redefine them, but merely
- define boolean typedef to int.
-
- * Makefile.in: Use $(DEFS) while compiling ansi2knr.
- * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS,
- because some C compilers do not like connectives with #ifdef.
- * m4.h: Define `volatile' only if __GNUC__, instead of once for
- __GNUC__ and once for __STDC__.
- * lib/regex.h: Leave const alone, AC_CONST will take care of it.
-
- * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for
- Makefile dependencies. Without it, make keeps destroying and
- remaking $(CHECKS) in a loop (why?). Distribute .all_stamp.

- to diversion/DIVERSION, this was a spelling error.
-
- * m4.c: Declare version[], remove #include "version.h".
- * version.h: Deleted.
- * Makefile.in: Remove references to version.h.
-
- * output.c (shipout_text): Centralize all `#line NUM ["FILE"]'
- production, by using a simpler and more robust algorithm. This
- solves the problem of synclines sometimes written in the middle of
- an output line. Delete sync_line() and output_lines variable.
- * m4.h: Remove sync_line prototype and output_lines declaration.
- * input.c (next_char), output.c (shipout_text): Remove references
- to output_lines.
- * input.c (push_file, pop_file): Merely put the value -1 in
- output_current_line instead of calling sync_line, for delaying a
- single `#line NUM FILE' before next output line. Do not test
- for sync_output, because this is unnecessary clutter.
- * output.c (make_divertion, insert_divertion): Idem.
- * input.c: Rename must_advance_line to start_of_input_line, for
- consistency.
-
- * debug.c (trace_header): Select a new debug line format, which
- better complies with GNU standards for formatting error messages.
- With option `-dfl', M-x next-error might be used on the output.
- * m4.c (vmesg): Adjust format of error output to GNU standards.
- * m4.texinfo: Adjust examples for `make check' to work.
-
- * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper

- * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of
- re_search_2.
- * lib/regex.[ch]: Use new version from textutils 1.3.6, with some
- collected patches. I tried a few times using newer regex.[ch], it
- mysteriously stopped aborting with this one. Insecure feeling...
- * lib/Makefile.in: Distribute regex.[ch].old, just in case!
-
-Fri Dec 18 11:08:03 1992 Francois Pinard (pinard at icule)
-

-
- * Makefile.in: Ensure recursive cleaning is done before local
- cleaning for all clean goals.
-
- * builtin.c (ntoa): Ensure the value is always interpreted as a
- signed quantity, whatever the radix is.
-

- out of file descriptors.
-
-Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
-
- * Makefile.in (realclean): Delete m4.info*.

-
-Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix)
-
- * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.'
- And use that only if __GNUC__ since we're using it's GCC-specific
- semantics that tell the compiler the associated function doesn't
- return.
-
- * builtin.c (substitute): Don't use character as an array index.
- (dumpdef_cmp): Make formal arguments `const void *' to avoid
- warnings with gcc -W -Wall on systems with qsort prototype.
- (m4_errprint): Cast obstack_finish to `char *' to avoid warnings
- from gcc -W -Wall.
-
- * eval.c (most functions): Add parentheses to assignments used
- as truth values go avoid warnings from gcc -Wall.

- any functions that don't need external scope.
-
- * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c

- removing the declaration from m4.h. Also rename false to FALSE
- and true to TRUE.
-
- * lib/Makefile.in (Makefile): New goal.
-
- * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not
- so heavily loaded. It gets more easily overridable, calling make.
- Reported by Jim Meyering.
-
- * Makefile.in (dist): Get .fname from the current directory name,
- instead of from version.h. I need updating many files manually,
- when the version changes, version.h is just one of them.
-
-Sat Nov 14 11:01:20 1992 Francois Pinard (pinard at icule)
-
- * m4.h: Remove the tag `boolean' on the enum introducing typedef
- `boolean'. This tag conflicts with <sys/types.h> on SVR4.
- Reported by Tom McConnell.
-
-Fri Nov 13 00:12:50 1992 Francois Pinard (pinard at icule)
-
- * m4.texinfo: Correct the examples for 33.divert, 38.divnum,
- 39.cleardiv, which were describing missing or spurious newlines.
- Modify examples 52.eval, 53.esyscmd and 54.sysval so the results
- do not depend on machine word size, `/bin/false' implementation,
- or `wc' output format. `make check' is more dependable, now.
-
- * checks/check_them: Summarize the failed tests by listing their
- name, at end. If none, issue `All checks successful'. Output
- `Checking' instead of `Input file:'.
-
- * checks/get_them, checks/check_them: Reindented.

- * Makefile.in (dist): chmod a+r before making the tar file.
-
-Thu Nov 12 14:42:57 1992 Francois Pinard (pinard at icule)
-
- * builtin.c (m4_dnl): Diagnose any parameter to `dnl'.
-
- * input.c (next_token): Reinitialize token_buttom just after using
- it as a watermark with obstack_free. Or else, a future token, big
- enough for triggering reallocation of the obstack chunk, could
- void the initialized value of token_buttom, later causing panic in
- obstack_free. Rename token_buttom to token_bottom everywhere.
-
- * m4.h: Before declaring errno, first include <errno.h> and
- ensure that it does not define errno.

- arguments. The last argument was silently ignored.
-
