Update to the current gnulib CVS repository, and fix trigraph handling in Bison. * bootstrap: Update gnulib CVS repository URL. (symlink_to_dir): Encapsulate the code that guarantees the destination directory exists into... (check_dst_dir): ... this new function, and... (cp_mark_as_generated): ... reuse it here so that bootstrap doesn't fail when copying files into lib/uniwidth/. * src/output.c (prepare_symbols): When writing yytname muscles, where symbol names will be encoded in C-string literals, tell quotearg to escape trigraphs. This used to be the default in gnulib. * tests/regression.at (Token definitions): Because of the change in gnulib's quotearg behavior, string_as_id in parse-gram.y no longer escapes trigraphs in symbol names. Thus, yytname no longer has trigraphs unnecessarily doubly escaped. Update test case output. Extend test case to be sure Bison's own error messages will no longer have trigraphs in symbol names unnecessarily escaped once.

* data/xslt/xml2dot.xsl (xsl:template match="automaton/state"): After 2007-10-11 change, the child elements here are items not rules. (<xsl:template match="item"): New. (xsl:template match="rule"): Update for new reduced itemset. (xsl:template match="point"): Remove. (xsl:template match="empty"): For consistency with --graph, don't output "/* empty */". * data/xslt/xml2text.xsl (xsl:template match="terminal"): When invoking line-wrap, don't pass a negative value as first-line-length since this won't work with the following changes. (xsl:template name="line-wrap"): Simplify slightly. (xsl:template name="ws-search"): Eliminate recursion. * src/print_graph.c (print_core): Don't print a reduction's lookahead set next to an item whose dot is not at the end of the RHS even if it happens to be associated with the same rule.

Make xml2dot.xsl and --graph produce the same output. * data/xslt/xml2dot.xsl (xsl:template match="rule"): Use a ' instead of a \n'. That is, don't add escapes yet or they'll be doubly escaped later. (xsl:template name="output-node"): Use the new escape template instead of the string-replace template directly. (xsl:template name="output-edge"): Likewise. (xsl:template name="escape"): New, escapes backslashes and newlines in addition to quotation marks. * src/graphviz.c (start_graph, output_node, output_edge): Add whitespace to output for legibility.

Improve C++ namespace support. Discussed starting at <http://lists.gnu.org/archive/html/help-bison/2007-09/msg00016.html>. * data/c++.m4: (b4_namespace_ref, b4_namespace_open, b4_namespace_close): New macros that interpret the %define variable "namespace" so its value can contain "::" to indicate nested namespaces. * data/glr.cc (b4_namespace): Don't define, and replace all uses with the above macros. * data/lalr1.cc (b4_namespace): Likewise. * data/location.cc (b4_namespace): Likewise. * doc/bison.texinfo (Decl Summary): Move %define push_pull' entry inside a new table in the general %define entry. Document %define namespace' there as well. Point the %name-prefix entry to it since it explains it more completely in the case of C++. (C++ Bison Interface): Mention %define namespace' instead of %name-prefix. (Table of Symbols): Remove the %define push_pull' entry. The %define entry suffices. * tests/c++.at (Relative namespace references): New test case. (Absolute namespace references): New test case. (Syntactically invalid namespace references): New test case. * tests/input.at (C++ namespace reference errors): New test case.

Add syncline support and location accessor to internal %define interfaces. * data/bison.m4 (b4_percent_define_get_loc): New. (b4_percent_define_get_syncline): New. (b4_percent_define_flag_if): Use b4_percent_define_get_loc. (b4_percent_define_default): Record defining location as line 1 rather than 0 for the sake of synchronizing #line's, and define b4_percent_define_syncline(VARIABLE). (b4_percent_define_check_values): Use b4_percent_define_get_loc. * src/muscle_tab.c (muscle_syncline_grow): New. (muscle_code_grow): Use muscle_syncline_grow. (muscle_percent_define_insert): Use muscle_percent_define_get_loc, and define b4_percent_define_syncline(VARIABLE). (muscle_percent_define_get_loc): New. (muscle_percent_define_get_syncline): New. (muscle_percent_define_flag_if): Use muscle_percent_define_get_loc, and remove some unused variables. (muscle_percent_define_default): Record defining location as line 1 rather than 0 for the sake of synchronizing #line's, and define b4_percent_define_syncline(VARIABLE). (muscle_percent_define_check_values): Use muscle_percent_define_get_loc. * src/muscle_tab.h (muscle_percent_define_get_loc): Prototype. (muscle_percent_define_get_syncline): Prototype. * tests/skeletons.at (%define Boolean variables: invalid skeleton defaults): Update output for location change. (Complaining during macro argument expansion): Extend to test b4_percent_define_get_loc and b4_percent_define_get_syncline errors.

Fix some error-reporting macro bugs. * data/bison.m4 (b4_cat): New. (b4_error, b4_error_at): Use b4_cat to send error directives directly to stdout so they don't become arguments to other macros. Update comments and add examples. (b4_warn, b4_warn_at, b4_complain, b4_complain_at): Update comments and add examples. (b4_fatal, b4_fatal_at): Likewise, and invoke m4_exit(1) immediately after printing the error directive so that M4 doesn't report subsequent problems that are induced by this problem. * src/scan-skel.l: Recognize @` digraph outside of directive arguments instead of just in them. Recognize @\n in both places. Both expand to the empty string. Needed by b4_cat. * tests/skeletons.at (Complaining during macro argument expansion): New test case. (Fatal errors make M4 exit immediately): New test case.

Replace %push-parser' and %push-pull-parser' with %define push_pull "push"' and %define push_pull "both"'. `%define push_pull "pull"' is the default. * doc/bison.texinfo (Push Decl, Push Parser Function, Pull Parser Function, Parser Create Function, Parser Delete Function): Update declarations. (Decl Summary, Table of Symbols): Replace %push-parser and %push-pull-parser entries with a %define push_pull entry. * data/bison.m4 (b4_percent_define_check_values): New macro. (b4_pull_if, b4_push_if, b4_use_push_for_pull_if): Move these definitions... * data/c.m4 (b4_identification): ... and the YYPUSH and YYPULL cpp definitions... * data/push.c: ... to here and compute them from the value of the %define variable push_pull. * data/c-skel.m4: Instead of choosing the push.c skeleton for push parsing requests here... * data/yacc.c: ... hack this to switch to push.c any time b4_use_push_pull_flag or the %define variable push_pull is set. This will go away when we mv push.c yacc.c. * data/c++-skel.m4, data/glr.c, data/java-skel.m4: Don't report that push parsing is not supported since unused %define variables are reported anyway. * src/getargs.c, src/getargs.h (pull_parser, push_parser): Remove. * src/muscle_tab.h (muscle_percent_define_check_values): Update comments for consistency with b4_percent_define_check_values. * src/output.c (prepare): Don't insert b4_pull_flag and b4_push_flag muscles. * src/parse-gram.y (PERCENT_PUSH_PARSER, PERCENT_PUSH_PULL_PARSER): Remove.
