Improve handling of multiple S/R conflicts in the same state and of S/R conflicts involving multiple reductions. * src/conflicts.c (resolve_sr_conflict): Don't assign the error action set for a state here or Bison will abort if it is reassigned on a later conflicted reduction in the same state. Similarly, don't finalize and assign the solved conflicts report here or it will be lost if it is reassigned on a later conflicted reduction in the same state.

Bruno Haible reported that the 2007-02-07 change would be dangerous in Turkish if we add a language whose name contains "i", since "i" is not lowercase "I" in Turkish. * bootstrap.conf (gnulib_modules): Add c-strcase. Remove strcase. * lib/.cvsignore: Add c-ctype.c, c-ctype.h, c-strcase.h, c-strcasecomp.c, c-strncasecmp.c. Remove strcasecmp.c, strncasecmp.c. * m4/.cvsignore: Remove strcase.m4. * src/getargs.c: Revert 2007-02-07 change, as follows. Include c-strcase.h.

Eventually, it should be possible to write an xgettext-like utility to extract @gettext<...@> text from skeletons. * data/bison.m4 (b4_check_user_names): Use @gettext<...@> when invoking b4_warn_at since b4_warn_at doesn't invoke gettext anymore. * data/glr.cc, data/lalr1.cc: Likewise but for b4_fatal and b4_complain reporting a push-parsing request or a missing %defines. * src/scan-skel.l (INITIAL): Recognize @gettext<' to start... (SC_AT_GETTEXT_ARG): ... this new start condition where gettext is invoked. (SC_AT_DIRECTIVE_ARG): Rename to... (SC_AT_DIRECTIVE_ARGS): ... this, and recognize @gettext<' to start SC_AT_GETTEXT_ARG. (at_directive_perform): Don't invoke gettext for @warn(...@), @warn_at(...@), etc. Instead, let the skeletons decide what should be passed to @gettext<...@>. * tests/skeletons.at (@gettext<...@>): New test case.

Implement support for relative and absolute skeleton file names. Discussed starting at <http://lists.gnu.org/archive/html/bison-patches/2006-12/msg00071.html>. * doc/bison.texinfo (Decl Summary): Document in %skeleton entry. (Bison Options): Document in --skeleton entry. * src/output.c (output_skeleton): Use strncpy rather than strcpy since full_skeleton can't necessarily hold all of pkgdatadir. If the specified skeleton file name contains a /', don't prepend pkgdatadir. * src/parse-gram.y (prologue_declaration): If the specified skeleton file name contains a /', prepend the grammar file directory. * tests/Makefile.am (TESTSUITE_AT): Add skeletons.at. * skeletons.at: New file. (relative skeleton file names): New test case. (installed skeleton file names): New test case. * tests/testsuite.at: Include skeletons.at.

* doc/bison.texinfo (Calc++ Parsing Driver): Let "parse" return an error code. (Calc++ Scanner): Exit with failure if we can't open the input file. Accept "-" standing for stdin. (Calc++ Top Level): Print the result only if the parsing was successful.

Clean up %define and %code implementation in M4 some. Most importantly, rename all related macros to be in the b4_percent_define and b4_percent_code namespaces. Also, complete support for .' in %define variable names and %code qualifiers. * data/bison.m4 (b4_check_user_names): Check for special "SKELETON-NAMESPACE(name)" macros instead of using two nested m4_foreach loops. (b4_get_percent_define, b4_get_percent_code): Rename to... (b4_percent_define_get, b4_percent_code_get): ... these. Extend documentation with examples. For SKELETON-NAMESPACE (as documented for b4_check_user_names), use b4_percent_define_skeleton_variables and b4_percent_code_skeleton_qualifiers. Expect any value for the %define variable foo' to be stored in the macro named b4_percent_define(foo)'; expect any %code blocks for the qualifier foo' to be stored in a macro named b4_percent_code(foo)'; expect any unqualified %code blocks to be stored in a macro named b4_percent_code_unqualified'. Use m4_indir so that %define variable names and %code qualifiers can contain `.', which is allowed by the grammar parser. (b4_percent_define_default): New macro to set a default value for a %define variable. (m4_wrap): Update wrapped code, and fix some underquoting. (b4_check_user_names_wrap): Update and define outside the m4_wrap. Expect grammar uses of %define variables and %code qualifiers to be defined in b4_percent_define_user_variables and b4_percent_code_user_qualifiers. * data/c++.m4: Use b4_percent_define_default rather than m4_define_default. Fix some underquoting. Skeleton usage of %define variable define_location_comparison now implies skeleton usage of %define variable filename_type. * data/glr.c, data/glr.cc, data/lalr1.cc, data/location.cc, data/push.c, data/yacc.c: Update macro names. * src/parse-gram.y (prologue_declaration, grammar_declaration): Update muscle names.

* djgpp/config.site: Set ac_cv_path_mkdir to a sane DJGPP specific default. Set gl_cv_absolute_wctype_h to a sane DJGPP specific default.

* tests/glr-regression.at: Use AT_PARSER_CHECK rather than AT_CHECK to run parsers in all tests so that Valgrind is invoked during maintainer-check-valgrind. (Duplicate representation of merged trees): Free all semantic values. (Duplicated user destructor for lookahead): Likewise.

* tests/local.at (AT_PARSER_CHECK): Add a PRE argument to specify a command-line prefix. * tests/torture.at (Exploding the Stack Size with Alloca): Stderr is ignored, so use that PRE to set --log-fd=1 in VALGRIND_OPTS so we don't miss Valgrind messages. (Exploding the Stack Size with Malloc): Likewise.

Ignore YYSTACK_USE_ALLOCA for push parsers since the stacks can't be locals. Reported by Juan Manuel Guerrero at <http://lists.gnu.org/archive/html/bug-bison/2007-01/msg00000.html>. * data/push.c: Enclose the #ifdef YYSTACK_USE_ALLOCA in b4_push_if. Fix some indentation also. * tests/torture.at (Exploding the Stack Size with Alloca): Add comment explaining this issue.

Simplify union and prologue handling, and escape union and lex/parse params with digraphs. * data/bison.m4 (b4_pre_prologue, b4_post_prologue): Set their default values to the empty string since these are no longer guaranteed initialized by the front-end. * data/glr.c, data/glr.cc, data/lalr1.cc, data/push.c, data/yacc.c: Add braces around b4_user_stype since this is no longer done by the front-end. * src/files.c, src/files.h (pre_prologue_obstack, post_prologue_obstack): Remove. * src/muscle_tab.c (muscle_pair_list_grow): Don't duplicate header comments here. Use MUSCLE_OBSTACK_SGROW so that values are escaped with digraphs. This fixes lex params and parse params. * src/muscle_tab.h (muscle_pair_list_grow): Update comments. * src/output.c (prepare): Remove muscle insertion of the prologues. (output): Remove freeing of pre_prologue_obstack and post_prologue_obstack. * src/parse-gram.y (prologue_declaration): Use muscle_code_grow rather than prologue_augment for prologue parsing so you don't need prologue obstacks. (grammar_declaration): Use `braceless' instead of "{...}" so that braces are already stripped and code is escaped with digraphs. * src/reader.c (prologue_augment): Remove. (reader): Remove initialization of pre_prologue_obstack and post_prologue_obstack. * src/reader.h (prologue_augment): Remove.

Remove quotes from variables names in %define directives and from qualifiers in %code directives, and restrict the characters that are allowed in them to M4-friendly ones. For %define, continue to support the quoted form as a deprecated feature. Discussed starting at <http://lists.gnu.org/archive/html/bison-patches/2007-01/msg00023.html>. * NEWS (2.3a+): Add entry for the change to %define. Update entry for %code. * doc/bison.texinfo (Prologue Alternatives): Update. (Bison Declaration Summary): In %defines entry, update mention of %code requires' and %code provides'. (C++ Location Values): Update %define uses. (Calc++ Parser Interface): Likewise. (Calc++ Parser): Likewise, and update %code requires' uses. (Bison Symbols): Update %code documentation. * src/parse-gram.y (prologue_declaration): For %define variables, use variable' instead of STRING'. (grammar_declaration): For %code qualifiers, use ID' instead of STRING'. (variable): New nonterminal that takes an ID' or a `STRING'. * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR): Update %code and %define uses. * tests/calc.at (_AT_DATA_CALC_Y): Update %define use. * tests/input.at (Reject unused %code qualifiers): Update %code uses. (%define errors): Update %define uses.
