Remove m4/glibc2.m4 (introduced by latest gnulib, but
we don't need it).
* lib/.cvsignore: Add dup-safer.c, fd-safer.c,
fopen-safer.c, stdio-safer.h, unistd-safer.h.
* lib/subpipe.c: Include "unistd-safer.h".
(create_subpipe): Make sure all the newly-created
file descriptors are > 2, so that diagnostics don't
get sent down them (which might cause Bison to hang, in theory).
* m4/.cvsignore: Add stdio-safer.m4, unistd-safer.m4.
* src/files.c (xfopen): Use fopen_safer, not fopen.
<http://lists.gnu.org/archive/html/bug-bison/2005-05/msg00042.html>.
* data/yacc.c (yyabortlab): Don't call destructor, and
don't set yychar to EMPTY.
(yyoverflowlab): Don't call destructor.
(yyreturn): Call destructor, if yychar is neither YYEOF nor YYEMPTY.
* tests/calc.at (AT_CHECK_CALC): Expect one fewer output lines,
since we no longer output the message "discarding lookahead token
end of input ()".
fix a small glitch in debugging output.
(yyprocessOneStack, yyrecoverSyntaxError, yyparse): Print newline
after YY_SYMBOL_PRINT where needed.
(struct yyGLRState): Add some comments.
(struct yySemanticOption): Add some comments.
(union yyGLRStackItem): Add comment.
(yymergeOptionSets): Correct this to properly perform the union,
avoiding infinite reported by Michael Rosien.
Update comment.
* tests/glr-regression.at: Add test for GLR merging error reported
by M. Rosien.
From Marcus Holland-Moritz.
* data/yacc.c (yyerrlab): Move the code that destroys the stack
from here....
(yyreturn): to here. That way, destructors are called properly
even if the stack overflows, or the user calls YYACCEPT or
YYABORT. Stack-overflow problem reported by Marcus Holland-Moritz.
(yyoverflowlab): Destroy the lookahead.
associated with tokens.
* src/output.c (prepare_symbols): Don't escape strings,
since users don't want to see C escapes.
* tests/calc.at (AT_CHECK_CALC): Adjust to lack of quotes
in diagnostics.
* tests/regression.at (Token definitions, Web2c Actions): Likewise.
(string_as_id): Quote $1 before using it as a key, since the
lexer no longer quotes it for us.
(string_content): Don't strip quotes, since lexer no longer
quotes it for us.
* src/scan-gram.l: Include quotearg.h.
("\""): Omit quote.
("'"<SC_ESCAPED_CHARACTER>): Quote symbol before using it as
a key, since the rest of the lexer doesn't quote it.
* src/symtab.c (symbol_get): Don't quote symbol; caller does it now.
* tests/regression.at (Token definitions): Check for backslashes
in token strings.
(YYSIZE_T): Define to unsigned long int when using an older compiler.
(yyparse): Revamp code to generate long syntax error message, to
make it easier to translate, and to avoid problems with arithmetic
overflow. Change "virtual memory" to "memory" in diagnostic, since
we don't know whether the memory is virtual.
translate strings.
* data/yacc.c (_) [!defined _]: New macro.
All English strings wrapped inside this macro.
* doc/bison.texinfo (Bison Parser): Document _.
* po/POTFILES.in: Include src/parse-gram.c, since it now
includes translateable strings that parse-gram.y doesn't.
escaped_file_name_output, since we now use it for symbol tags as
well. All uses changed.
(symbol_destructors_output, symbol_printers_output):
Escape symbol tags too.
Problem reported by Matyas Forstner in
<http://lists.gnu.org/archive/html/bug-bison/2005-03/msg00009.html>.
* src/muscle_tab.c (muscle_code_grow): Don't quote numbers; it's
not needed.
* src/output.c (user_actions_output, token_definitions_output,
symbol_destructors_output, symbol_printers_output): Likewise.
* src/reader.c (prologue_augment): Likewise.
* src/scan-gram.l (handle_action_dollar, handle_action_at): Likewise.
