| * 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... |

| 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. |

| |
| Release 1.3. |

| * src/m4.h: Adjust declaration for prefix_all_buitins. |
| * src/builtin.c (builtin_init): Merge in functionality from |
| previous prefix_all_buitins function, while making entries in the |

| |
| * src/freeze.c (reload_frozen_state): Add a useless `break;', |
| because *many* compilers do not accept an empty `default:'. |

| |
| * stackovf.c (setup_stackovf_trap): Replace "Don't" by "Do not" in |

| Reported by Andreas Schwab, Jim Meyering and Joseph E. Sacco. |
| |
| * Makefile.in (install): Have install depend on all too, for lib |
| to be remade as needed. |
| |

| |
| 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, |
| instead of using sscanf which stops as soon as there is a |
| non-digit in the input. Previously, incr(1xyzzy), eval(1,2xyzzy) |
| and divert(1xyzzy) were all accepted without any warning or error |
| messages. |
| * m4.h: Declare strtol as long if not including stdlib.h. |

| |
| * stackovf.c: Isolated OS-dependent sections; Improved portability, |
| adding support for SunOS/BSD (sigvec, sigstack, and 4-parameter signal |
| 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. |

| 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. |
| |

| 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. |

| 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 |

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

| 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__. |
| Reported by Eric Backus. |
| |
| * configure.in: Substitute CFLAGS and LDFLAGS, taking their value |
| from the environment. Default CFLAGS to -g if not set. |
| * Makefile.in: Have CFLAGS and LDFLAGS substituted from configure. |
| * lib/Makefile.in: Have CFLAGS substituted from configure. |
| Reported by Eric Backus and Tom McConnell. |
| |
| * 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. |

| Declare TOKEN_DATA_FUNC macro. |
| * builtin.c: Declare changeword. |
| (m4_changeword): New function. |

| (input_init): Initialize the word regexp. |
| (set_word_regexp): New. |
| (next_token): Declare local variables, use the previous code if |
| default_word_regexp is true. Else, match using a new code. Save |
| the original text. |
| * macro.c (expand_token): Ship out original text if not a macro |
| 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. |

| 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. |
| |
| * m4.c: Declare warning_status, initialize it to 0. Add new |
| option -E, or --fatal-warnings, which sets warning_status to |
| EXIT_FAILURE instead. |

| |
| * format.c (format): When not HAVE_EFGCVT, m4 was failing the |

| first, delaying the fetch of the corresponding argument. |
| Reported by Joseph E. Sacco and Tom Quinn. |
| |

| Tue Jan 25 18:39:37 1994 Francois Pinard (pinard at icule) |
| |

| * 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. |

| 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 |

| to diversion/DIVERSION, this was a spelling error. |

| * 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) |
| |

| 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. |

| signed quantity, whatever the radix is. |
| |
| Wed Nov 18 07:57:19 1992 Jim Meyering (meyering@idefix) |

| * 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. |

| 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'. |
| |

| |
| * *.[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. |
| |
| * m4.h: Before declaring errno, first include <errno.h> and |
| ensure that it does not define errno. |
| Reported by Richard Stallman. |
| |
| Wed Nov 11 17:40:35 1992 Francois Pinard (pinard at icule) |
| |
| * builtin.c: Define and use DECLARE macro for builtins. |
| |
| * builtin.c (m4_ifelse): Avoid any diagnostic when exactly one |
| argument, this is a common idiom for introducing long comments. |
| |
| * builtin.c (m4_ifelse): If 3n + 2 arguments, diagnose missing |
| arguments. The last argument was silently ignored. |
| |
| * m4.c (cmd_error): Add a missing semicolon before va_end(). |
| |

| * ansi2knr.c: New, from Ghostscript distribution. |
| * configure.in: Define U through FP_PROTOTYPES for old compilers. |
| Add AC_ISC_POSIX, AC_CONST, AC_SIZE_T. |

| (xfree): Accept void * instead of char *. |
| (xmalloc): Return void * instead of char *. |
| (xrealloc): Accept and return void * instead of char *. |
| * macro.c: Protoized. |
| * output.c: Protoized. |

| |
| * m4.texinfo: Remove directory from diagnostics in 30.include, |
| 51.eval, 56.errprint and 57.m4exit tests. |
| |
| * m4.h: Remove declarations for int or void system functions, they |
| cause more conflicting trouble than they make good. |
| |
| * configure.in: Avoid configuration header file. Add some tests. |
| * m4.h: Remove #include "config.h". |
| * Makefile.in, lib/Makefile.in: Implement Autoconf interface. |

| |
| * format.c (format): Avoid syntax error if not HAVE_EFGCVT, |

| |
| * m4.c: Accept --no-warnings instead of --no_warnings, and |
