Reported by Eric Backus.
Wed Nov 2 00:47:53 1994 Francois Pinard (pinard@icule)
* src/freeze.c (produce_frozen_state): If the frozen file cannot
be opened, return immediately after producing the error message.
Reported by Andreas Schwab.
* configure.in: Check for const only after having found possible
ANSIfying compiler flags, this is of no use to check it before.
Reported by Alexander Lehmann.
Tue Nov 1 22:02:37 1994 Francois Pinard (pinard@icule)
* src/macro.c (collect_arguments): Cast obstack arguments to
(voidstar), so avoiding compiler warnings.
Reported by Joseph E. Sacco.
* src/freeze.c (produce_frozen_state): Cast printed lengths to
(int) so they correspond to %d format items.
Reported by Joseph E. Sacco.

constant string m4 and variable or parameter named version.
Sun Oct 30 08:13:03 1994 Francois Pinard (pinard@icule)
* src/m4.h, src/debug.c: Replace all #ifdef __STDC__ by #if
__STDC__. Alliant FX/2800 Concentrix 2.2 (i860-BSD4.3) compiler
defines __STDC__ to 0, for indicating it is *not* ANSI!
Reported by Kaveh R. Ghazi.
* configure.in: Added obsolescent tests for AIX and Minix.
* doc/Makefile.in (mostlyclean): Remove texclean in dependencies,
which texclean does not exist anymore.
Reported by Eric Backus, Jim Meyering, John David Anglin and
Joseph E. Sacco.
Sat Oct 29 05:10:03 1994 Francois Pinard (pinard@icule)
* aclocal.m4 (fp_C_PROTOTYPES): Force -D_HPUX_SOURCE with -Aa.
Reported by John David Anglin.
* src/ansi2knr.c: New version, sent by Peter Deutsch.
* aclocal.m4 (fp_C_PROTOTYPES): Substitute empty or ansi2knr for
ANSI2KNR, depending on the fact the compiler is ANSI or not.
* src/Makefile.in: Use -Ovarargs=convert on ansi2knr calls.
Remove the sed filter after ansi2knr for debug.c. Use $O instead
of $U, put underline in extensions rather than in basenames. Use
implicit rules, now that regularity makes this possible.
Have $(OBJECTS) depend on $(ANSI2KNR), so to trigger compilation
of ansi2knr whenever it is needed.
* configure.in: Adjusted for correct STACKOVF substitution.
* src/debug.c (trace_format): When not __STDC__, use (...) as a
parameter list, so ansi2knr will convert it to (va_alist) va_dcl.

* configure.in: Do not add -O to CFLAGS for GNU C, now that
configure does it automatically.
Reported by Jim Meyering.
Fri Sep 23 08:16:58 1994 Francois Pinard (pinard@icule)

* Release 1.3.
* Makefile.in: Group all *clean-recursive goals in one, using sed
to remove `-recursive' while calling make recursively. Also, use
a subshell for each recursive $(MAKE).
Reported by Jim Meyering.
* src/m4.h (memcpy): Define with bcopy for BSD systems.
Reported by Kaveh R. Ghazi.
* src/Makefile.in (ansi2knr): Use $(LIBS) while linking, for SunOS

* Makefile.in (distclean, realclean): Force serial execution of
both goals, in case parallel makes are being used.
Reported by Jim Meyering.
* src/Makefile.in (DISTFILES): Distribute TAGS.
(distclean): Do not remove TAGS.
(realclean): Remove it.
Reported by Karl Berry.
Sat Sep 10 12:34:04 1994 Francois Pinard (pinard@icule)
* configure.in: Use fp_ to match aclocal.m4. Revert _OS_ macros
to old names, for following Autoconf.
Thu Sep 8 15:07:27 1994 Francois Pinard (pinard@icule)
* Makefile.in (MDEFINES): Remove INSTALL substitutions, for

* configure.in: Correct stack overflow detection logic, taking
care of systems having only incomplete implementations (like for
Pyramid 9820 OSx 5.0d).

frozen. Do not call builtin_init when reloading frozen state.
Speed up diversion processing:
* output.c: Add INITIAL_BUFFER_SIZE, MAXIMUM_BUFFER_SIZE,

reallocate_diversion_for and OUTPUT_CHARACTER.
(shipout_text, make_diversion, insert_diversion): Adapted to new
structures.
(insert_file): Use better buffering.
Reported by David MacKenzie.

Reported by Jim Avera and Joseph E. Sacco.
Tue Jul 12 06:54:31 1994 Francois Pinard (pinard@icule)
* Makefile.in (check): Have it depend on all instead of m4. In
this way, a change in lib will be detected and processed.
* builtin.c (numeric_arg): Use strtol and verify the conversion,

handlers), and a default error message if the fault address is not
available (when neither siginfo.h nor BSD sigcontext are supported).
* configure.in: Changes for stackovf.h: Check for sigcontext,
sigaction, sigstack, and define rlim_t as int if necessary.
* acconfig.h: Added HAVE_SIGCONTEXT and rlim_t.
* examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow.
* ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax.

Reported by Ian Taylor.
Sat Jul 2 00:58:47 1994 Francois Pinard (pinard@icule)
* configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS,
because siginfo.h is unrelated to standard headers, and siginfo.h
is already checked for.
Reported by Joseph E. Sacco.

PROTOTYPES.
* aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by
AC_PROTOTYPES.
Wed Jun 29 22:41:53 1994 Francois Pinard (pinard@icule)
* builtin.c (substitute): Use \& to represent this part of the
string which was matched by the whole regexp, instead of
representing the whole string. Any usage of \0 issues a warning
and acts like \&, it will disappear in some subsequent release.
Mon Jun 27 14:24:23 1994 Francois Pinard (pinard@icule)
* m4.c: Complete prototype for forwarded declaration of usage.
* input.c (init_macro_token): Correct own reference in error
message. Previous name get_macro_func was referred to instead.
(next_char): Correct own reference in error message. Previous
name advance_input was referred to instead.
* m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits.
* eval.c (logical_or_term, logical_and_term, or_term, xor_term,
and_term, not_term, logical_not_term, cmp_term, shift_term,
add_term, mult_term, exp_term, unary_term, simple_term): Add
prototype to forwarded declarations. Declare parameter v1 as
eval_t * instead of int *. Same for local variable v2 in dyadic
functions. Same for result in exp_term.
* builtin.c (m4_eval): Declare value as eval_t instead of int.
(ntoa): Declare value as eval_t instead of int. Declare uvalue as
unsigned_eval_t instead of unsigned int. Change casts accordingly.

Reported by Thorsten Ohl.
* macro.c: Complete the prototypes of forwarded expand_macro and
expand_token.
Reported by Thorsten Ohl.

Reported by Tom McConnell.
* ansi2knr.1: New, from elsewhere.
* Makefile.in (DISTFILES): Distribute ansi2knr.1
* Makefile.in (stamp-h.in): Avoid running ./config.status if
stamp-h does not exist yet. This avoids running it a second time
just after the initial ./configure.
Reported by David MacKenzie and Tom McConnell.
* m4.h: Replace the enum debug_info declaration with a series of
#define's. The Ultrix 3.1 compiler would otherwise need casting
(int) to most references, when used in expressions.
Reported by Tom McConnell.
Sat Jun 25 00:10:05 1994 Francois Pinard (pinard@icule)
* aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES,
following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES
calls the compiler. Previously, FP_PROTOTYPES was only calling
the preprocessor; by not being subject to CFLAGS, this was
discouraging those flags asking for ANSI compilation.
* acconfig.h: Document HAVE_PROTOTYPES.
* configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES.
* m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__.

* configure.in: m4_undefine changeword before using AC_ENABLE.
* m4.h: Declare prototypes for error (for ANSI compilers only),
prefix_all_builtins and reference_error.
Reported by Tom McConnell.
* input.c (set_word_regexp): Do not try to initialize the array
test from a string, this does not work with non-ANSI compilers.
Reported by Eric Backus.
* Makefile.in (dist): Clean examples/ before saving it.
(distclean-local): Also remove stamp-h.
Reported by Eric Backus.
* Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with
non ANSI compilers.
Reported by Tom McConnell.
* checks/Makefile.in (clean): Depends on mostlyclean.
(mostlyclean): New goal.

name.
Reported by Krste Asanovic and Pete Chown.
[These modifs all depend upon ENABLE_CHANGEWORD]
* m4.h: Declare external user_word_regexp.
* m4.c: Declare user_word_regexp, and initialize it from
--word-regexp or -W, or NULL if not specified.
* 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.
* checks/Makefile.in: Empty the suffix list.
Reported by Geoff Russell, Joel Sherrill and Roland McGrath.
* m4.c: Declare nesting_limit and initialize it to 250.
Implement -LNUMBER or --nesting-limit=NUMBER to change its
value.
* m4.h: Declare nesting_limit as external.
* macro.c (expand_macro): Stop execution whenever nesting limit
is exceeded.
Reported by Bengt Mertensson.
* eval.c (evaluate): Diagnose excess characters in eval input.
Things like `eval(08)' used to return 0 with no diagnostic.
* m4.h: Capitalize first letter of all macro arguments in
definitions.

* configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note
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
49.format check, abusing a `union values' argument with sprintf
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
not HAVE_EFGCVT, because a NUL may be forced into it.
* m4.h: Declare atof() when not STDC_HEADERS.
Reported by Joseph E. Sacco.

Reported by Jim Meyering.
Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule)

inclusion of system files, because they may define it first.
Tue Jan 4 19:46:50 1994 Francois Pinard (pinard@icule)
* checks/Makefile.in (CHECKS): Add a useless `*' before `[', to
get around a problem with Alpha make seeing a syntax error, there.
Reported by Vern Paxson.
Mon Jan 3 00:21:45 1994 Francois Pinard (pinard@icule)

string, with reference_error, which prints it on standard error.
* builtin.c, output.c: Use errno as second parameter to error,
instead of using syserr() with %s.
* *.c: Use M4ERROR instead of error: no more errref() with %s.
Doing so, the program name appears after the input reference
instead of before, which eases M-x next-error processing.
Wed Nov 24 22:16:15 1993 Francois Pinard (pinard@icule)
* checks/get-them: Escape braces with backslashes in patterns,
because HPUX-9.01 awk needs this.

macros, replace error_message_prefix() declaration by errref()'s.
Declare xrealloc, for use in errref().
* m4.c: Delete error_message_prefix() function, add errref().
* *.c: Use error() systematically in place of all error macros,
now that error() flushes stdout first. Make needed adjustments.
* m4.h: Remove const in sys_errlist[] declaration, it creates
conflicts on SGI and Alpha.
Reported by Kaveh R. Ghazi.

* builtin.c (m4_eval): Cast strlen to (int) before comparing.
* input.c (input_init): Initialize quote and comment strings
explicitely instead of calling set_quotes and set_comment: by
doing so, we ensure we do not free uninitialized variables.
* checks/check-them: Reverse arguments to both diff, so the
expected is on the left and the obtained on the right.
* m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR
macros. Delete declarations for m4error, warning, fatal and
internal_error, add declaration for error_message_prefix.

Delete debug_print and debug_message routines, add
debug_message_prefix routine.
* builtin.c, debug.c: Replace debug_print routine calls with
DEBUG_PRINT* macro calls.

* debug.c: Include <stdarg.h> or <varargs.h>.
(trace_format): Use stdarg instead of varargs if __STDC__.

Uong, Ian Taylor, Kaveh R. Ghazi, Tom McConnell and Walter Wong.
Mon Nov 8 21:11:44 1993 Francois Pinard (pinard@icule)

instead of the other way around.
* builtin.c, m4.c, path.c: Use strchr instead of index.
* input.c (next_char): Remove a "break;" after a "return ...;".

* 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.
* m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION
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
case for enum debug_info constants, which were all lower case.
* 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)
* m4.c: Change `--no-warnings' to `--silent'.
Reported by David MacKenzie.
* m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and
leave it off for now. See comment in m4.c for justification.
Reported by David MacKenzie.
* configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h).
* m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H.
* Makefile.in: Add a new `info' goal. Use macro MAKEINFO.
* 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.
Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix)
* builtin.c, format.c, input.c: Split long lines.
* m4.c: Use typedef macro_definition instead of struct
macro_definition.
* symtab.c: Use typedef symbol instead of struct symbol.
Tue Nov 17 01:58:40 1992 Francois Pinard (pinard at icule)
* *.[ch]: Remove all trailing whitespace, in code and comments.
* configure.in: Find some awk.
* Makefile.in: Add $(AWK) to MDEFINES.
* checks/Makefile.in: Transmit $(AWK) to get_them.
* checks/get_them: Use $AWK instead of gawk. Add a close in the
awk script when switching files, because without this, mawk runs
out of file descriptors.
Mon Nov 16 20:42:56 1992 Francois Pinard (pinard at icule)
* Makefile.in (realclean): Delete m4.info*.
Reported by Jim Meyering.
* Makefile.in: Adjust and link with checks/Makefile.
* checks/Makefile.in: New.
* configure.in: Output checks/Makefile.
* checks/get_them: Have the dnl header of each test more
recognizable by next-error, also use a better message.
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.
* input.c, m4.c, output.c, path.c, symtab.c: Declare static
any functions that don't need external scope.
* builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c
(many functions and arrays): Declare `const'.
Sun Nov 15 09:42:09 1992 Francois Pinard (pinard at icule)
* *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>,
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.

missing or superflous arguments to built-in macros.
* Added default options via the M4OPTS environment variable.
* The built-in format can now be configured to use sprintf as
the formatting engine, for systems without [efg]cvt(3).

Francois Pinard and Roland H. Pesch for providing me with reports.
* The builtins incr and decr are now implemented without use of
eval.
* The builtin indir is added, to allow for indirect macro calls
(allows use of "illegal" macro names).
* The debugging and tracing facilities has been enhanced
considerably. See the manual for details.
* The -tMACRO option is added, marks MACRO for tracing as soon
as it is defined.
* Builtins are traced after renaming iff they were before.
* Named files can now be undiverted.
* The -Nnum option can be used to increase the number of
divertions available.
* Calling changecom without arguments now disables all comment
handling.
* The function m4_patsubst() is now consistently declared
static.
* A bug in dnl is fixed.
* A bug in the multi-character quoting code is fixed.

* Updated and enhanced version. Release 0.75, manual 0.07.
* Implemented search path for include files (-I option and
M4PATH envronment variable).
* Implemented builtin "format" for printf-like formatting.
* Implemented builtin "regexp" for searching for regular
expressions.
* Implemented builtin "patsubst" for substitution with regular
expressions.

* Implemented control over debugging output.
* Implemented multi-character quotes.
* Implemented multi-character comment delimiters.
