* src/complain.c (warning_issued): Renamed from warn_message_count; now bool.
(complaint_issued): Renamed from complain_message_count; likewise.
* src/main.c (main): Use exit to exit with failure.
* src/complain.c (fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS
rather than 1 and 0.
* src/main.c (main): Likewise.
* src/getargs.c (getargs): Likewise.
* src/reader.c (reader): Likewise.
* src/getarg.c (getargs): Remove duplicate code for
"Try `bison --help'".
* src/files.c (xfopen, xfclose): Use EXIT_FAILURE rather than 2.
What was that "2" for?
* src/complain.h (fatal, fatal_at): Add __attribute__((__noreturn__)).
* src/getargs.c (usage): Likewise.
* src/getargs.c (getargs): When there are too few operands, report
the last one. When there are too many, report the first extra
one. This is how diffutils does it.
so that we needn't worry about integer overflow (!).
Now of type bool. All uses changed.
(complaint_issued): Renamed from complain_message_count; likewise.
(fatal_at, fatal): Use EXIT_FAILURE and EXIT_SUCCESS rather than 1 and 0.
Include <limits.h> unconditionally, since it's guaranteeed even
for a freestanding C89 compiler.
(SHRT_MIN, SHRT_MAX): Remove, since C89 guarantees them.
arguments and output `void'.
(b4_c_function): Rename as...
(b4_c_function_def): this.
(b4_c_function_decl, b4_c_ansi_function_def)
(b4_c_ansi_function_decl): New.
Change the interpretation of the arguments: before `int, foo', now
`int foo, foo'.
* data/yacc.c (yyparse): Prototype and define thanks to these.
Adjust b4_c_function_def uses.
* data/glr.c (yyparse): Likewise, but ANSI only.
(m4_invoke): Remove decl.
(scan_skel): New decl.
(output_skeleton): Use pipe rather than temporary file for m4 input.
Check that m4sugar.m4 is readable, to avoid deadlock.
Check for pipe I/O error.
float, as this generates a warning on Solaris 8 + GCC 3.2 with
--enable-gcc-warnings. Instead, divide into 1.0 rather than 1;
this generates a more-accurate value anyway.
(timervar_accumulate): Rename local variables to avoid confusion
with similarly-named global 'start_time'.
LEX_PRE_FORMALS, LEX_ARGS, LEX_PRE_ARGS, USE_LEX_ARGS.
Use them to have `calc.y' ready for %pure-parser.
* data/yacc.c (YYLEX): Pass a yylex return type to
b4_c_function_call.
* src/parse-gram.y: Add the definition of the %lex-param and
%parse-param tokens, plus their rules.
Drop the `_' version of %glr-parser.
Add the "," token.
* src/scan-gram.l (INITIAL): Scan them.
* src/muscle_tab.c: Comment changes.
(muscle_insert, muscle_find): Rename `pair' as `probe'.
* src/muscle_tab.h (MUSCLE_INSERT_PREFIX): Remove unused.
(muscle_entry_s): The `value' member is no longer const.
Adjust all dependencies.
* src/muscle_tab.c (muscle_init): Adjust: use
MUSCLE_INSERT_STRING.
Initialize the obstack earlier.
* src/muscle_tab.h, src/muscle_tab.c (muscle_grow)
(muscle_pair_list_grow): New.
* data/c.m4 (b4_c_function_call, b4_c_args): New.
* data/yacc.c (YYLEX): Use b4_c_function_call to honor %lex-param.
* tests/calc.at: Use %locations, not --locations.
(AT_CHECK_CALC_GLR): Use %glr-parser, not %glr_parser.
accordingly.
Report the traditional `Try ... --help' message when status != 0.
(usage, version): Don't take a FILE * as arg, it is pointless.
(getargs): When there is an incorrect number of arguments, make it
an error, and report it GNUlically thanks to `usage ()'.
