Include a 4421 description for debugging flags. 4422 4423Fri Jul 29 10:15:52 1994 François Pinard (pinard@icule) 4424 4425 * configure.in: If sigaction is available and SA_ONSTACK defined, 4426 use sigaction. Otherwise, if sigvec is available and SV_ONSTACK 4427 defined, use sigvec. Else don't compile stackovf.c. 4428 * stackovf.c (setup_stackovf_trap): Idem. 4429 Reported by Jim Avera, Karl Berry, Kaveh R. Ghazi, Matthias Rabe 4430 and Simon Leinen. 4431 4432Thu Jul 21 22:43:17 1994 François Pinard (pinard@icule) 4433 4434 * m4.c (usage): Replace printf par fputs. 4435 4436Mon Jul 18 23:48:23 1994 François Pinard (pinard@icule) 4437 4438 * Release 1.2 4439 4440Sun Jul 17 08:08:25 1994 François Pinard (pinard@icule) 4441 4442 * configure.in: Check for sigaction and sigvec. Add a new delayed 4443 check for RLIMIT_STACK, combine in the checking for getrlimit. 4444 All those things are not universally available. 4445 * stackovf.c: Split setting up the trap handler and catching 4446 signals, for better taking care of various configure outcomes. 4447 * examples/stackovf.sh: Correct a typo. 4448 Reported by Eric Backus, Jim Avera and Jim Meyering. 4449 4450Sat Jul 16 20:36:19 1994 François Pinard (pinard@icule) 4451 4452 * ansi2knr.c: New version sent by its author, Peter Deutsch. 4453 4454Fri Jul 15 14:36:21 1994 François Pinard (pinard@icule) 4455 4456 * Makefile.in: Modify so parallel make will not try making 4457 lib/libm4.a twice simultaneously. 4458 Reported by Jim Meyering. 4459 4460Thu Jul 14 17:23:17 1994 François Pinard (pinard@icule) 4461 4462 * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in 4463 error message, for when no code possibility exists. Even if this 4464 line is completely #ifdef'ed out, it brings a syntax error. 4465 Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco. 4466 4467 * Makefile.in (install): Have install depend on all too, for lib 4468 to be remade as needed. 4469 4470 * examples/stackovf.sh: Try ksh, bsh and bash for shells 4471 providing ulimit, instead of using only ksh. 4472 Reported by Jim Avera and Joseph E. Sacco. 4473 4474Tue Jul 12 06:54:31 1994 François Pinard (pinard@icule) 4475 4476 * Makefile.in (check): Have it depend on all instead of m4. In 4477 this way, a change in lib will be detected and processed. 4478 4479 * builtin.c (numeric_arg): Use strtol and verify the conversion, 4480 instead of using sscanf which stops as soon as there is a 4481 non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy) 4482 and divert(1xyzzy) were all accepted without any warning or error 4483 messages. 4484 * m4.h: Declare strtol as long if not including stdlib.h. 4485 * configure.in: Check for limits.h, and replace strtol if missing. 4486 * lib/Makefile.in: Substitute LIBOBJS. Distribute strtol.c. 4487 * lib/strtol.c: New file, from elsewhere. 4488 Reported by Andreas Schwab. 4489 4490Thu Jul 7 22:38:10 1994 François Pinard (pinard@icule) 4491 4492 * macro.c (expand_macro): Cast value to (boolean) prior to 4493 assigning it to traced. 4494 Reported by Tom McConnell. 4495 4496 * Makefile.in (m4): Always make all in lib first. 4497 Reported by Jim Meyering. 4498 4499Wed Jul 6 13:16:31 1994 Jim Avera (jima@netcom.com) 4500 4501 * stackovf.c: Isolated OS-dependent sections; Improved portability, 4502 adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal 4503 handlers), and a default error message if the fault address is not 4504 available (when neither siginfo.h nor BSD sigcontext are supported). 4505 * configure.in: Changes for stackovf.h: Check for sigcontext, 4506 sigaction, sigstack, and define rlim_t as int if necessary. 4507 * acconfig.h: Added HAVE_SIGCONTEXT and rlim_t. 4508 * examples/stackovf.sh: Run m4 -L99999999 to allow stack overflow. 4509 * ansi2knr.c: Fix for func-ptr args; convert "..." to varargs syntax. 4510 4511Tue Jul 5 19:13:54 1994 François Pinard (pinard@icule) 4512 4513 * configure.in: Use AC_SET_MAKE. 4514 * Makefile.in: Use @SET_MAKE@. 4515 Reported by Jim Meyering. 4516 4517 * checks/check-them: Do not trap on SIGQUIT or SIGALRM. 4518 Reported by Ian Taylor. 4519 4520Sat Jul 2 00:58:47 1994 François Pinard (pinard@icule) 4521 4522 * configure.in: Remove dependency of USE_STACKOVF on STDC_HEADERS, 4523 because siginfo.h is unrelated to standard headers, and siginfo.h 4524 is already checked for. 4525 Reported by Joseph E. Sacco. 4526 4527 * acconfig.h, aclocal.m4, m4.h: Replace HAVE_PROTOTYPES by 4528 PROTOTYPES. 4529 * aclocal.m4, configure.in: Replace AC_HAVE_PROTOTYPES by 4530 AC_PROTOTYPES. 4531 4532Wed Jun 29 22:41:53 1994 François Pinard (pinard@icule) 4533 4534 * builtin.c (substitute): Use \& to represent this part of the 4535 string which was matched by the whole regexp, instead of 4536 representing the whole string. Any usage of \0 issues a warning 4537 and acts like \&, it will disappear in some subsequent release. 4538 4539Mon Jun 27 14:24:23 1994 François Pinard (pinard@icule) 4540 4541 * m4.c: Complete prototype for forwarded declaration of usage. 4542 4543 * input.c (init_macro_token): Correct own reference in error 4544 message. Previous name get_macro_func was referred to instead. 4545 (next_char): Correct own reference in error message. Previous 4546 name advance_input was referred to instead. 4547 4548 * m4.h: Declare eval_t and unsigned_eval_t typedefs to 32 bits. 4549 * eval.c (logical_or_term, logical_and_term, or_term, xor_term, 4550 and_term, not_term, logical_not_term, cmp_term, shift_term, 4551 add_term, mult_term, exp_term, unary_term, simple_term): Add 4552 prototype to forwarded declarations. Declare parameter v1 as 4553 eval_t * instead of int *. Same for local variable v2 in dyadic 4554 functions. Same for result in exp_term. 4555 * builtin.c (m4_eval): Declare value as eval_t instead of int. 4556 (ntoa): Declare value as eval_t instead of int. Declare uvalue as 4557 unsigned_eval_t instead of unsigned int. Change casts accordingly. 4558 (shipout_int): Cast first argument of ntoa to eval_t. 4559 Reported by Thorsten Ohl. 4560 4561 * macro.c: Complete the prototypes of forwarded expand_macro and 4562 expand_token. 4563 Reported by Thorsten Ohl. 4564 4565 * m4.h: Define voidstar as void * or char * depending on __STDC__. 4566 The Ultrix 3.1 compiler cannot do much with void pointers. 4567 4568 * builtin.c (dumpdef_cmp): Replace void * by voidstar. 4569 * m4.c (xfree): Replace void * by voidstar. 4570 Reported by Tom McConnell. 4571 4572 * ansi2knr.1: New, from elsewhere. 4573 * Makefile.in (DISTFILES): Distribute ansi2knr.1 4574 4575 * Makefile.in (stamp-h.in): Avoid running ./config.status if 4576 stamp-h does not exist yet. This avoids running it a second time 4577 just after the initial ./configure. 4578 Reported by David MacKenzie and Tom McConnell. 4579 4580 * m4.h: Replace the enum debug_info declaration with a series of 4581 #define's. The Ultrix 3.1 compiler would otherwise need casting 4582 (int) to most references, when used in expressions. 4583 Reported by Tom McConnell. 4584 4585Sat Jun 25 00:10:05 1994 François Pinard (pinard@icule) 4586 4587 * aclocal.m4: Replace FP_PROTOTYPES by AC_HAVE_PROTOTYPES, 4588 following an idea from Brook G. Milligan. AC_HAVE_PROTOTYPES 4589 calls the compiler. Previously, FP_PROTOTYPES was only calling 4590 the preprocessor; by not being subject to CFLAGS, this was 4591 discouraging those flags asking for ANSI compilation. 4592 * acconfig.h: Document HAVE_PROTOTYPES. 4593 * configure.in: Use AC_HAVE_PROTOTYPES instead of FP_PROTOTYPES. 4594 * m4.h: Define _() according to HAVE_PROTOTYPES, not __STDC__. 4595 Reported by Eric Backus. 4596 4597 * configure.in: Substitute CFLAGS and LDFLAGS, taking their value 4598 from the environment. Default CFLAGS to -g if not set. 4599 * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure. 4600 * lib/Makefile.in: Have CFLAGS substituted from configure. 4601 Reported by Eric Backus and Tom McConnell. 4602 4603 * configure.in: m4_undefine changeword before using AC_ENABLE. 4604 4605 * m4.h: Declare prototypes for error (for ANSI compilers only), 4606 prefix_all_builtins and reference_error. 4607 Reported by Tom McConnell. 4608 4609 * input.c (set_word_regexp): Do not try to initialize the array 4610 test from a string, this does not work with non-ANSI compilers. 4611 Reported by Eric Backus. 4612 4613 * Makefile.in (dist): Clean examples/ before saving it. 4614 (distclean-local): Also remove stamp-h. 4615 Reported by Eric Backus. 4616 4617 * Makefile.in (_stackovf.c): Goal for compiling stacokovf.c with 4618 non ANSI compilers. 4619 Reported by Tom McConnell. 4620 4621 * checks/Makefile.in (clean): Depends on mostlyclean. 4622 (mostlyclean): New goal. 4623 4624Fri Jun 24 23:30:31 1994 François Pinard (pinard@icule) 4625 4626 * Makefile.in (DISTFILES): Distribute install.sh. 4627 * install.sh: New file, copied from elsewhere. 4628 Reported by Assar Westerlund and Kaveh R. Ghazi. 4629 4630Thu Jun 23 00:00:30 1994 François Pinard (pinard@icule) 4631 4632 * configure.in: Define ENABLE_CHANGEWORD if --enable-changeword. 4633 * acconfig.h: Explain ENABLE_CHANGEWORD. 4634 4635 [These modifs all depend upon ENABLE_CHANGEWORD and are adapted 4636 from code provided by Pete Chown] 4637 * m4.h: Add original_text field to u_t variant of union u. 4638 Declare TOKEN_DATA_FUNC macro. 4639 * builtin.c: Declare changeword. 4640 (m4_changeword): New function. 4641 * input.c: Include "regex.h", define variables with word regexps. 4642 (input_init): Initialize the word regexp. 4643 (set_word_regexp): New. 4644 (next_token): Declare local variables, use the previous code if 4645 default_word_regexp is true. Else, match using a new code. Save 4646 the original text. 4647 * macro.c (expand_token): Ship out original text if not a macro 4648 name. 4649 Reported by Krste Asanovic and Pete Chown. 4650 4651 [These modifs all depend upon ENABLE_CHANGEWORD] 4652 * m4.h: Declare external user_word_regexp. 4653 * m4.c: Declare user_word_regexp, and initialize it from 4654 --word-regexp or -W, or NULL if not specified. 4655 * input.c: Use user_word_regexp if specified, instead of 4656 DEFAULT_WORD_REGEXP. 4657 4658 * Makefile.in (m4): Revert Jan 3 1994 change. I'm unable to 4659 agree with it. 4660 4661 * Makefile.in, lib/Makefile.in: Limit suffixes to .c and .o. 4662 * checks/Makefile.in: Empty the suffix list. 4663 Reported by Geoff Russell, Joel Sherrill and Roland McGrath. 4664 4665 * m4.c: Declare nesting_limit and initialize it to 250. 4666 Implement -LNUMBER or --nesting-limit=NUMBER to change its 4667 value. 4668 * m4.h: Declare nesting_limit as external. 4669 * macro.c (expand_macro): Stop execution whenever nesting limit 4670 is exceeded. 4671 Reported by Bengt Mertensson. 4672 4673 * eval.c (evaluate): Diagnose excess characters in eval input. 4674 Things like `eval(08)' used to return 0 with no diagnostic. 4675 4676 * m4.h: Capitalize first letter of all macro arguments in 4677 definitions. 4678 4679 * m4.c: Declare warning_status, initialize it to 0. Add new 4680 option -E, or --fatal-warnings, which sets warning_status to 4681 EXIT_FAILURE instead. 4682 * m4.h: Declare external warning_status. Define EXIT_SUCCESS and 4683 EXIT_FAILURE if not otherwise done by header files. 4684 * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE. 4685 * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c, 4686 eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first 4687 argument of all M4ERROR calls. 4688 Reported by Noah Friedman. 4689 4690 * examples/incl-test.m4: Renamed from incl_test.m4. 4691 * examples/include.m4: Include incl-test.m4 instead of 4692 incl_test.m4. 4693 * examples/multiquotes.m4: Renamed from multi-quotes.m. 4694 4695Wed Jun 22 21:58:54 1994 François Pinard (pinard@icule) 4696 4697 * configure.in: Avoid USE_STACKOVF if <siginfo.h> not found. Note 4698 that Jim developped stackovf.c on a 486 running SVR4.0 (ESIX), and 4699 also tested it on a Sun Sparc workstation running SunOS 4.x. 4700 4701 * format.c (format): When not HAVE_EFGCVT, m4 was failing the 4702 49.format check, abusing a `union values' argument with sprintf 4703 without selecting the proper field. Now, save the formatting type 4704 first, delaying the fetch of the corresponding argument. 4705 Reported by Joseph E. Sacco and Tom Quinn. 4706 4707 * format.c (format): Remove const from char *fmt declaration when 4708 not HAVE_EFGCVT, because a NUL may be forced into it. 4709 4710 * m4.h: Declare atof() when not STDC_HEADERS. 4711 Reported by Joseph E. Sacco. 4712 4713 * Regenerate configure using Autoconf 1.11, this corrects a 4714 problem about an incorrect cpp seting on NeXT 3.1. 4715 Reported by Alexander Lehmann. 4716 4717Sun Jun 5 16:25:19 1994 François Pinard (pinard@icule) 4718 4719 * m4.h (_): Change argument from `x' to `Args'. 4720 4721Wed May 4 23:59:39 1994 François Pinard (pinard@icule) 4722 4723 * Makefile.in: Remove all occurrences of $(MFLAGS), which were 4724 bringing more evil than good on a few systems. 4725 Reported by Greg A. Woods. 4726 4727Fri Apr 22 15:59:35 1994 François Pinard (pinard@icule) 4728 4729 * m4.h: Rename Args() to _(). 4730 * m4.h: Remove extern specifier from all function declarations. 4731 4732Fri Apr 22 15:51:21 1994 Jim Avera (jima@netcom.com) 4733 4734 * stackovf.c: New file implementing stack-overflow detection. 4735 * configure.in: Check for getrlimit, sigaction. If all of 4736 standard headers, getrlimit and sigaction, define USE_STACKOVF and 4737 substitute ${U}stackovf.o for STACKOVF. 4738 * acconfig.h: Declare USE_STACKOVF. 4739 * Makefile.in: Distribute stackovf.c, link with $(STACKOVF). 4740 * m4.h: Declare setup_stackovf_trap(). 4741 * m4.c: Call setup_stackovf_trap(). 4742 * tests/stackovf_test.sh: New file. 4743 4744Wed Apr 13 14:10:30 1994 François Pinard (pinard@icule) 4745 4746 * checks/Makefile.in: Rename .all-stamp to stamp-checks. 4747 4748 * Makefile.in (Makefile, etc.): Adapt for Autoconf 1.8. 4749 4750Sun Jan 30 14:24:19 1994 (pinard at icule) 4751 4752 * m4.h: Remove definition of volatile, not used anymore. 4753 Reported by Jim Meyering and Joseph E. Sacco. 4754 4755 * m4.h: Consistently use `do { ... } while (0)' in macros, instead 4756 of `if ... else /* nothing */' for if macros. 4757 Reported by Jim Meyering. 4758 4759 * builtin.c (m4_regexp): Reorganize the code for avoiding a 4760 warning from gcc about `repl' possibly used before defined. 4761 Reported by Jim Meyering. 4762 4763 * m4.h: Avoid a pre-ANSI <memory.h> together with <string.h>. 4764 Reported by Jim Meyering. 4765 4766Tue Jan 25 18:39:37 1994 François Pinard (pinard at icule) 4767 4768 * m4.h: Move the conditional definition of volatile after the 4769 inclusion of system files, because they may define it first. 4770 4771Tue Jan 4 19:46:50 1994 François Pinard (pinard@icule) 4772 4773 * checks/Makefile.in (CHECKS): Add a useless `*' before `[', to 4774 get around a problem with Alpha make seeing a syntax error, there. 4775 Reported by Vern Paxson. 4776 4777Mon Jan 3 00:21:45 1994 François Pinard (pinard@icule) 4778 4779 * Makefile.in: Do not define LDFLAGS, use CFLAGS on link calls. 4780 Reported by Richard Stallman. 4781 4782Sat Dec 25 08:06:05 1993 François Pinard (pinard@icule) 4783 4784 * configure.in: Correct test for strerror, AC_FUNC_CHECK was used 4785 instead of AC_HAVE_FUNCS. 4786 Reported by Noah Friedman. 4787 4788Wed Dec 1 09:37:53 1993 François Pinard (pinard@icule) 4789 4790 * m4.c: Initialize show_help and show_version to zero. 4791 4792 * m4.c: Ensure EXIT_SUCCESS and EXIT_FAILURE are defined. 4793 Use them in exit() and usage() calls. 4794 4795Sat Nov 27 10:43:24 1993 François Pinard (pinard@icule) 4796 4797 * m4.h: Delete extern sys_nerr, sys_errlist declarations, and 4798 syserr() macro. Delete errref, add reference_error and M4ERROR. 4799 * m4.c: Replace errref, which was returning an input reference 4800 string, with reference_error, which prints it on standard error. 4801 * builtin.c, output.c: Use errno as second parameter to error, 4802 instead of using syserr() with %s. 4803 * *.c: Use M4ERROR instead of error: no more errref() with %s. 4804 Doing so, the program name appears after the input reference 4805 instead of before, which eases M-x next-error processing. 4806 4807Wed Nov 24 22:16:15 1993 François Pinard (pinard@icule) 4808 4809 * checks/get-them: Escape braces with backslashes in patterns, 4810 because HPUX-9.01 awk needs this. 4811 Reported by Jim Meyering. 4812 4813Mon Nov 22 10:55:52 1993 François Pinard (pinard@icule) 4814 4815 * builtin.c: Declare "FILE *popen ();". 4816 4817 * m4.h: Remove MESSAGE{,1,2}, WARNING1, FATAL{,1}, INTERNAL_ERROR 4818 macros, replace error_message_prefix() declaration by errref()'s. 4819 Declare xrealloc, for use in errref(). 4820 * m4.c: Delete error_message_prefix() function, add errref(). 4821 * *.c: Use error() systematically in place of all error macros, 4822 now that error() flushes stdout first. Make needed adjustments. 4823 4824 * m4.h: Remove const in sys_errlist[] declaration, it creates 4825 conflicts on SGI and Alpha. 4826 Reported by Kaveh R. Ghazi. 4827 4828Sat Nov 20 08:26:15 1993 François Pinard (pinard@icule) 4829 4830 * m4.c: Include <getopt.h> instead of "getopt.h". 4831 4832 * configure.in: Output to config.h. Use HAVE_FUNCS preferably. 4833 * acconfig.h: New, for documenting HAVE_EFGCVT. 4834 * Makefile.in: Distribute acconfig.h, .stamp-h.in and config.h.in, 4835 use them wherever appropriate. Also use -I. for compilations. 4836 * lib/Makefile.in: Use -I.. for compilations. 4837 * *.c: Include <config.h> or "config.h". 4838 4839 * m4.h: Test for HAVE_MEMORY_H instead of NEED_MEMORY_H. 4840 * configure.in: Use AC_HAVE_HEADERS(memory.h), delete AC_MEMORY_H. 4841 4842Wed Nov 17 09:34:55 1993 François Pinard (pinard@icule) 4843 4844 * builtin.c (m4_eval): Cast strlen to (int) before comparing. 4845 4846 * input.c (input_init): Initialize quote and comment strings 4847 explicitely instead of calling set_quotes and set_comment: by 4848 doing so, we ensure we do not free uninitialized variables. 4849 4850 * checks/check-them: Reverse arguments to both diff, so the 4851 expected is on the left and the obtained on the right. 4852 4853 * m4.h: Add MESSAGE{,1,2}, WARNING1, FATAL{,1} and INTERNAL_ERROR 4854 macros.

Woods. 5147 5148Sun Dec 20 10:40:20 1992 François Pinard (pinard at icule) 5149 5150 * Makefile.in: Remove $(CPPFLAGS) from the .c.o rule. The user 5151 might well use CFLAGS is s/he needs it. 5152 5153 * Makefile.in: Allow installation of info files from a separate 5154 build directory. 5155 Reported by Jason Merrill. 5156 Reported by David MacKenzie. 5157 Reported by Skip Montanaro. 5158 Reported by Erez Zadok. 5159 Reported by Assar Westerlund. 5160 5161Sat Dec 19 08:21:34 1992 François Pinard (pinard at icule) 5162 5163 * Release 1.0.3 5164 This is still a beta release for the future GNU m4 version 1.1. 5165 5166 * lib/alloca.c: New, from elsewhere. 5167 * lib/Makefile.in: Distribute it. Define and use $(ALLOCA). 5168 5169 * m4.h: Do not define index/rindex if already defined. If 5170 FALSE/TRUE are already defined, do not redefine them, but merely 5171 define boolean typedef to int. 5172 5173 * Makefile.in: Use $(DEFS) while compiling ansi2knr. 5174 * ansi2knr.c: Rewrite #ifdef HAVE_STRING_H || STDC_HEADERS, 5175 because some C compilers do not like connectives with #ifdef. 5176 * m4.h: Define `volatile' only if __GNUC__, instead of once for 5177 __GNUC__ and once for __STDC__. 5178 * lib/regex.h: Leave const alone, AC_CONST will take care of it. 5179 5180 * checks/Makefile.in: Use .all_stamp instead of $(CHECKS) for 5181 Makefile dependencies. Without it, make keeps destroying and 5182 remaking $(CHECKS) in a loop (why?). Distribute .all_stamp. 5183 5184 * m4.h, m4.c, builtin.c, output.c: Change all divertion/DIVERTION 5185 to diversion/DIVERSION, this was a spelling error. 5186 5187 * m4.c: Declare version[], remove #include "version.h". 5188 * version.h: Deleted. 5189 * Makefile.in: Remove references to version.h. 5190 5191 * output.c (shipout_text): Centralize all `#line NUM ["FILE"]' 5192 production, by using a simpler and more robust algorithm. This 5193 solves the problem of synclines sometimes written in the middle of 5194 an output line. Delete sync_line() and output_lines variable. 5195 * m4.h: Remove sync_line prototype and output_lines declaration. 5196 * input.c (next_char), output.c (shipout_text): Remove references 5197 to output_lines. 5198 * input.c (push_file, pop_file): Merely put the value -1 in 5199 output_current_line instead of calling sync_line, for delaying a 5200 single `#line NUM FILE' before next output line. Do not test 5201 for sync_output, because this is unnecessary clutter. 5202 * output.c (make_divertion, insert_divertion): Idem. 5203 * input.c: Rename must_advance_line to start_of_input_line, for 5204 consistency. 5205 5206 * debug.c (trace_header): Select a new debug line format, which 5207 better complies with GNU standards for formatting error messages. 5208 With option `-dfl', M-x next-error might be used on the output. 5209 * m4.c (vmesg): Adjust format of error output to GNU standards. 5210 * m4.texinfo: Adjust examples for `make check' to work. 5211 5212 * m4.h, builtin.c, debug.c, input.c, macro.c, path.c: Use upper 5213 case for enum debug_info constants, which were all lower case. 5214 5215 * builtin.c (m4_regexp, m4_patsubst): Use re_search instead of 5216 re_search_2. 5217 * lib/regex.[ch]: Use new version from textutils 1.3.6, with some 5218 collected patches. I tried a few times using newer regex.[ch], it 5219 mysteriously stopped aborting with this one. Insecure feeling... 5220 * lib/Makefile.in: Distribute regex.[ch].old, just in case! 5221 5222Fri Dec 18 11:08:03 1992 François Pinard (pinard at icule) 5223 5224 * m4.c: Change `--no-warnings' to `--silent'. 5225 Reported by David MacKenzie. 5226 5227 * m4.c: Put all M4OPTS code upon IMPLEMENT_M4OPTS control, and 5228 leave it off for now. See comment in m4.c for justification. 5229 Reported by David MacKenzie. 5230 5231 * configure.in: Replace AC_USG by AC_HAVE_HEADERS(string.h). 5232 * m4.h, ansi2knr.c, lib/regex.h: Replace USG by HAVE_STRING_H. 5233 5234 * Makefile.in: Add a new `info' goal. Use macro MAKEINFO. 5235 5236 * Makefile.in: Ensure recursive cleaning is done before local 5237 cleaning for all clean goals. 5238 5239 * builtin.c (ntoa): Ensure the value is always interpreted as a 5240 signed quantity, whatever the radix is. 5241 5242Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix) 5243 5244 * builtin.c, format.c, input.c: Split long lines. 5245 * m4.c: Use typedef macro_definition instead of struct 5246 macro_definition. 5247 * symtab.c: Use typedef symbol instead of struct symbol. 5248 5249Tue Nov 17 01:58:40 1992 François Pinard (pinard at icule) 5250 5251 * *.[ch]: Remove all trailing whitespace, in code and comments. 5252 5253 * configure.in: Find some awk. 5254 * Makefile.in: Add $(AWK) to MDEFINES. 5255 * checks/Makefile.in: Transmit $(AWK) to get_them. 5256 * checks/get_them: Use $AWK instead of gawk. Add a close in the 5257 awk script when switching files, because without this, mawk runs 5258 out of file descriptors. 5259 5260Mon Nov 16 20:42:56 1992 François Pinard (pinard at icule) 5261 5262 * Makefile.in (realclean): Delete m4.info*. 5263 Reported by Jim Meyering. 5264 5265 * Makefile.in: Adjust and link with checks/Makefile. 5266 * checks/Makefile.in: New. 5267 * configure.in: Output checks/Makefile. 5268 5269 * checks/get_them: Have the dnl header of each test more 5270 recognizable by next-error, also use a better message. 5271 5272Mon Nov 16 07:48:52 1992 Jim Meyering (meyering@idefix) 5273 5274 * m4.h [__GNUC__]: Use __volatile__ instead of `volatile.' 5275 And use that only if __GNUC__ since we're using it's GCC-specific 5276 semantics that tell the compiler the associated function doesn't 5277 return. 5278 5279 * builtin.c (substitute): Don't use character as an array index. 5280 (dumpdef_cmp): Make formal arguments `const void *' to avoid 5281 warnings with gcc -W -Wall on systems with qsort prototype. 5282 (m4_errprint): Cast obstack_finish to `char *' to avoid warnings 5283 from gcc -W -Wall. 5284 5285 * eval.c (most functions): Add parentheses to assignments used 5286 as truth values go avoid warnings from gcc -Wall. 5287 5288 * input.c, m4.c, output.c, path.c, symtab.c: Declare static 5289 any functions that don't need external scope. 5290 5291 * builtin.c, debug.c, format.c, m4.c, m4.h, macro.c, symtab.c 5292 (many functions and arrays): Declare `const'. 5293 5294Sun Nov 15 09:42:09 1992 François Pinard (pinard at icule) 5295 5296 * *.[ch]: Rename nil to NULL, using the declaration from <stdio.h>, 5297 removing the declaration from m4.h. Also rename false to FALSE 5298 and true to TRUE. 5299 5300 * lib/Makefile.in (Makefile): New goal. 5301 5302 * Makefile.in, lib/Makefile.in: Add a .c.o rule, so CFLAGS is not 5303 so heavily loaded. It gets more easily overridable, calling make. 5304 Reported by Jim Meyering. 5305 5306 * Makefile.in (dist): Get .fname from the current directory name, 5307 instead of from version.h. I need updating many files manually, 5308 when the version changes, version.h is just one of them. 5309 5310Sat Nov 14 11:01:20 1992 François Pinard (pinard at icule) 5311 5312 * m4.h: Remove the tag `boolean' on the enum introducing typedef 5313 `boolean'. This tag conflicts with <sys/types.h> on SVR4. 5314 Reported by Tom McConnell. 5315 5316Fri Nov 13 00:12:50 1992 François Pinard (pinard at icule) 5317 5318 * m4.texinfo: Correct the examples for 33.divert, 38.divnum, 5319 39.cleardiv, which were describing missing or spurious newlines. 5320 Modify examples 52.eval, 53.esyscmd and 54.sysval so the results 5321 do not depend on machine word size, `/bin/false' implementation, 5322 or `wc' output format. `make check' is more dependable, now. 5323 5324 * checks/check_them: Summarize the failed tests by listing their 5325 name, at end. If none, issue `All checks successful'. Output 5326 `Checking' instead of `Input file:'. 5327 5328 * checks/get_them, checks/check_them: Reindented. 5329 5330 * Makefile.in (dist): chmod a+r before making the tar file. 5331 5332Thu Nov 12 14:42:57 1992 François Pinard (pinard at icule) 5333 5334 * builtin.c (m4_dnl): Diagnose any parameter to `dnl'. 5335 5336 * input.c (next_token): Reinitialize token_buttom just after using 5337 it as a watermark with obstack_free. Or else, a future token, big 5338 enough for triggering reallocation of the obstack chunk, could 5339 void the initialized value of token_buttom, later causing panic in 5340 obstack_free.
