* data/bison.m4 (b4_percent_define_if_define_): Also map dashes to
underscores.
* src/scan-gram.l ({id}): Also accept dashes after the initial
letter.
({directive}): Use {id}.
* src/parse-gram.y: Comment and formatting changes.
* doc/bison.texinfo (Symbols): Adjust the lexical definitions of
symbols.
* src/complain.h, src/complain.c (yacc_at): New.
* src/symtab.c (symbol_new): Use yacc_at to report inappropriate
symbol names.
* src/output.c (token_definitions_output): Do not #define token
names with dashes.
* tests/local.at (AT_MATCHES_CHECK): New.
Based on Perl instead of Sed. Sed has too many portability
pitfalls, not ever Sed is GNU Sed.
* tests/actions.at (Fix user actions without a trailing semicolon):
Use it.
(cherry picked from commit 6617622c9a)
if it seems necessary.
* src/scan-code.l (flex rules section): Flag cpp directive from
any `#' to the first unescaped end-of-line. Semicolon is not
needed after `;', `{', '}', or cpp directives and is needed after
any other token (whitespaces and comments have no effect).
* tests/actions.at (Fix user actions without a trailing semicolon):
New test.
* tests/input.at (AT_CHECK_UNUSED_VALUES): Add semicolons to
to make user actions complete statements.
Adjust column numbers in error messages.
* tests/regression.at (Fix user actions without a trailing semicolon):
Remove. Covered by new test.
(cherry picked from commit e8cd1ad655)
* tests/output.at (AT_CHECK_OUTPUT_FILE_NAME): Avoid tripping
autoconf bug related to # in test.

* src/getargs.h, src/getargs.c (locations_flag): Remove.
* src/getargs.c, src/scan-code.l: Use muscle_percent_define_ensure
to set "locations" to true.

b4_percent_define_if_define.

Suggested by Joel E. Denny.

New, extracted from...
* src/parse-gram.y (prologue_declaration: pure-parser): here.
Remove it.

src/scan-gram.l (actual name passed as the first argument)
with special case for %define.
* doc/Makefile.am (doc/cross-options.texi): Pass src/scan-gram.l
to build-aux/cross-options.pl.
* src/getargs.c (usage): Document limitations of cross-options.pl.
* src/scan-gram.l: Likewise.
* src/getargs.h, src/getargs.c (skeleton_arg, language_argmatch):
The location argument is now mandatory.
Adjust all dependencies.
(getargs): Use command_line_location.
* src/getargs.c (quotearg.h, muscle_tab.h): Include.
(getargs): Define file_name.
* src/main.c (main): Initialize muscle_tab before calling
getargs.
* src/muscle_tab.c (muscle_init): No longer define file_name, as
its value is not available yet.
* build-aux/cross-options.pl: As in --help output, write optional
arguments as [=ARG] not =[ARG].
* doc/bison.texinfo (Bison Options): Add -W/--warnings argument.
* build-aux/cross-options.pl: As in --help output, write optional
arguments as [=ARG] not =[ARG].
