This is not just nicer, it is also much safer, since we were
using sprintf...

Adjust dependencies.

This is warning, and it seems there are no means to make it an error.

clause.

Currently "%printer {...} a b c d e f" translates the {...} six times.
Not only is this bad for time and space, it also issues six times the
same warnings.
* src/symlist.h, src/symlist.c (symbol_list_destructor_set)
(symbol_list_printer_set): Take the action as code_props instead of
const char *.
* src/parse-gram.y: Translate these actions here.
* src/scan-code.h: Comment change.
* tests/input.at: Check that warnings are issued only once.
The conversion from @ to @@ and so forth is coded is too many
different places. Factor, a bit.
* src/scan-code.l: Instead of duplicating the logic of obstack_escape,
use it.
It sure is less efficient, but the cost is negligible.
This allows to factor rules that are alike.
And to factor some start-condition clauses.
* tests/input.at (Stray $ or @): New.
* NEWS: Document it.
* src/scan-code.l, src/scan-skel.l: Use a more traditional indentation
style for start-conditions.
Prefer "continue" to a comment, for empty actions.
Strip useless {}.
Remove useless start-condition clauses.
* src/scan-code.l (SC_SYMBOL_ACTION): Accept $<tag>$, not just $$.
* data/c.m4 (b4_dollar_dollar_): New.
(b4_symbol_actions): Let b4_dollar_dollar use b4_dollar_dollar_.
* NEWS, doc/bison.texi: Document it.
* tests/actions.at: Check this for C and C++.
* src/output.c (quoted_output): Split into...
(quoted_output, string_output): these.
Use the former when outputting a type_name.
* tests/input.at: Check this case.
* src/symtab.h: Comment changes.
* src/scan-code.l: Use obstack_quote when passing type_name to m4.
* tests/input.at (Code injection): New.
* NEWS: Document it.
Thanks to Paul Eggert for the wording.
* src/system.h (obstack_quote): New.
* src/muscle-tab.c: Use it instead of obstack_escape where applicable.
* src/scan-code.l: Since obstack_quote supports NULL, leave type_name
as NULL instead of defaulting to "".
* src/muscle-tab.c (MUSCLE_COMMON_DECODE, muscle_string_decode)
(muscle_location_decode): Not related to muscles, rename as...
(COMMON_DECODE, string_decode, location_decode): these.
* src/muscle-tab.h (MUSCLE_OBSTACK_SGROW): This is not related to
muscles, so move to, and rename as...
* src/system.h (obstack_escape): this.
Adjust dependencies.
Currently they are treated in separated variables, contrary to other
<TYPE> code_props. This duplicates code (and messages for translators)
uselessly, as demonstrated by the fact that thanks to this patch, now
useless <*> and <> code_props are reported like the others.
* src/parse-gram.y (generic_symlist_item): Treat "<*>" and "<>" as regular
type tags.
* src/symlist.h, src/symlist.c (symbol_list_default_tagged_new)
(symbol_list_default_tagless_new,SYMLIST_DEFAULT_TAGGED)
(SYMLIST_DEFAULT_TAGLESS): Remove.
* src/symtab.h, src/symtab.c (default_tagged_code_props)
(default_tagless_code_props, default_tagged_code_props_set)
(default_tagless_code_props_set): Remove.
(symbol_code_props_get): Default to <*> or <>'s code_props.
* tests/actions.at: Complete expected errors: there are new warnings.
* tests/input.at: Likewise.
(Useless printers or destructors): Extend.
The logic to compute the %printer or %destructor to used (i.e., a
code_props) is implemented twice: one, of course, in
symbol_code_props_get, and another time in symbol_check_defined to
record the fact that a code_props is used (so that we can reported
unused ones). Let the former use the latter.
I would probably use "mutable" in C++ and keep these guys const,
but this is C. And casting away constness triggers warnings.
* src/scan-code.h, src/scan-code.l (code_props_none): Is not const.
* src/symtab.h, src/symtab.c (symbol_code_props_get): The symbol
is not const.
(symbol_check_defined): Use it.
* data/glr.c, data/glr.cc, data/lalr1.cc, data/lalr1.java, data/yacc.c:
Since the previous commit, b4_tokens_define and the like no longer need
b4_tokens.
* src/output.c (token_definitions_output): Remove.
A function to print warnings categories, like -Wyacc, -Wother, etc.
* src/complain.h, src/complain.c (print_warning_categories): New function.
* src/output.c (ARRAY_CARDINALITY): Move it to file 'src/system.h'.
* src/complain.h (enum warnings): New value, 'silent', "complain"
must not display the warning type.
Forthcoming changes will use the warning categories much more often,
so shortening them will improve readability.
* src/complain.c, src/complain.h, src/conflicts.c,
* src/getargs.c, src/getargs.h, src/gram.c (enum warnings):
s/warnings_/W/g.
* origin/maint:
tests: use the generalized default yylex.
tests: AT_YYERROR_DEFINE: prepare for list of ints.
skeletons: no longer define YYLSP_NEEDED.
c++: do not export YYTOKEN_TABLE and YYERROR_VERBOSE.
