* 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.
(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'.
it confused me, and I was the author! Instead, assume that people
who want to use K&R C compilers (when using these modules in GCC,
perhaps?) will run ansi2knr.
bitsetv_ones, bitsetv_transitive_closure, bitsetv_dump,
debug_bitsetv): Use function prototypes; this removes the need for
declaring static functions simply to provide their prototypes.
bitset_andn_or_cmp_, bitset_bytes, bitset_copy_, bitset_count_,
bitset_create, bitset_dump, bitset_first, bitset_free, bitset_init,

bitset_prev, bitset_print, bitset_release_memory, bitset_toggle_,

debug_bitset): Use function prototypes; this removes the need for
declaring static functions simply to provide their prototypes.
tests/cxx-type.at, tests/headers.at, tests/input.at,
tests/regression.at, tests/synclines.at, tests/torture.at:
Say "bison -o foo.c foo.y", not "bison foo.y -o foo.c",
so that the tests still work even if POSIXLY_CORRECT is set.
* doc/bison.texinfo (Rpcalc Compile, Invocation): Likewise.
for portability to K&R hosts. Fix typo: signed char is guaranteed
only to 127, not to 128.
* data/glr.c (yysigned_char): New type.
* data/yacc.c (yysigned_char): Likewise.
* tests/regression.at (Web2c Actions): signed char -> yysigned_char.
<http://mail.gnu.org/pipermail/bug-bison/2002-October/001670.html>:
"nonterm: { $$ = 123; } { $$ = $1; };" was wrongly rejected,
because the Bison parser reads the second action before reducing
the first one.
* src/scan-gram.l (rule_length): New static var.
Use it to keep track of the rule length in the scanner, since
we can't expect the parser to be in lock-step sync with the scanner.
(handle_action_dollar, handle_action_at): Use this var.
* tests/actions.at (Exotic Dollars): Test for the problem.
Use it to keep track of the rule length in the scanner, since
we can't expect the parser to be in lock-step sync with the scanner.
(handle_action_dollar, handle_action_at): Use this var.
Update copyright date and clarify comments.
(get_time) [IN_GCC]: Keep the GCC version for reference.
Merge GCC changes. Change "GCC" to "Bison" in the copyright notice.

(lbitset_bytes): Adjust to new, unique names for structures.

lbitset_empty_p, lbitset_ones, lbitset_not, lbitset_subset_p,

(enum_lbitset_find_mode): New type. All instances of parameters of
type enum FOO are now of type enum_FOO, to conform to the C Standard.
(struct lbitset_struct, lbitset, bitset_struct, PFV): Remove.
(lbitset_and, lbitset_andn, lbitset_or, lbitset_xor): New functions.
objects. Do not assume that adding a header size to a multiple of a
word size yields a value that is properly aligned for the whole union.
(bitsetv_alloc): Add a cast to (void *) to avoid a GCC warning.
(union bitset_union, struct abitset_struct, struct ebitset_struct,
struct lbitset_struct, struct bitset_stats_struct): New types.
All uses of struct bitset_struct changed to union bitset_union,
etc.
(bitset_next, bitset_prev, bitset_only_set_p): Declare.
All instances of parameters of type enum bitset_opts are now of
type enum_bitset_opts, to conform to the C Standard, and similarly
for enum_bitset_type.
(bitset): Now points to a union, not to a struct.
All instances of "struct bitset_struct *" replaced with "bitset".
(bitset_and_or_, bitset_andn_or_, bitset_or_and_): New decls.
(abitset_bytes): Return a size that is aligned
properly for vectors of objects. Do not assume that adding a
header size to a multiple of a word size yields a value that is
properly aligned for the whole union.

that GCC can do.
(struct abitset_struct, abitset, struct bitset_struct): Remove.
the same width as int. This reapplies a hunk of the 2002-08-12 patch
<http://mail.gnu.org/pipermail/bison-patches/2002-August/001111.html>,
which was inadvertently undone by the 2002-09-30 patch.
* lib/lbitset.c (debug_lbitset): Do not assume that bitset_word is
the same width as int.
