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.

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.

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. + + * m4.c: Declare warning_status, initialize it to 0. Add new + option -E, or --fatal-warnings, which sets warning_status to + EXIT_FAILURE instead. + * m4.h: Declare external warning_status. Define EXIT_SUCCESS and + EXIT_FAILURE if not otherwise done by header files. + * m4.c: Delete declarations for EXIT_SUCCESS and EXIT_FAILURE. + * m4.c, input.c, output.c, symtab.c, builtin.c, macro.c, debug.c, + eval.c: Replace 0 by warning_status and 1 by EXIT_FAILURE in first + argument of all M4ERROR calls. + Reported by Noah Friedman. + + * examples/incl-test.m4: Renamed from incl_test.m4. + * examples/include.m4: Include incl-test.m4 instead of + incl_test.m4. + * examples/multiquotes.m4: Renamed from multi-quotes.m. + +Wed Jun 22 21:58:54 1994 Francois Pinard (pinard@icule) + + * 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.

Release 0.99, manual 0.09. Many thanks to + 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. + + * Several typos in the manual has been corrected. More probably + persist. + + * The m4.info file is now installed along with the program. + +Thu Nov 15 21:51:06 1990 Rene' Seindal (seindal at diku.dk) + + * 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 builtin "esyscmd", which expands to a shell + commands output. + + * Implemented "__file__" and "__line__" for use in error + messages. + + * Implemented character ranges in "translit". + + * Implemented control over debugging output. + + * Implemented multi-character quotes. + + * Implemented multi-character comment delimiters. + + * Changed predefined macro "gnu" to "__gnu__". + + * Changed predefined macro "unix" to "__unix__", when the -G + option is not used. With -G, "unix" is still defined. + + * Changed "shift", "$@" and "$*" to not insert spaces afters + commas. + + * Added program name to error messages. + + * Fixed two missing null bytes bugs. + +Mon Jan 22 21:08:52 1990 Rene' Seindal (seindal at diku.dk) + + * Initial beta release.
