+       * src/symtab.c (symbol_make_alias): Set type of SYMVAL to be
+       that of SYM's type.  This fixes Debian bug 168069, reported by
+       Thomas Olsson.
+

+
+       Version 1.75f.
+
+       Switch back to the Yacc style of conflict reports, undoing some
+       of the 2002-07-30 change.
+       * doc/bison.texinfo (Understanding): Use Yacc style for
+       conflict reports.  Also, use new way of locating rules.
+       * src/conflicts.c (conflict_report):
+       Renamed from conflict_report_yacc, removing the old
+       'conflict_report'.  Translate the entire conflict report at once,
+       so that we don't assume that "," has the same interpretation in
+       all languages.
+       (conflicts_output): Use Yacc-style conflict report for each state,
+       instead of our more-complicated style.
+       (conflicts_print): Use Yacc-style conflict report, except print
+       the input file name when not emulating Yacc.
+       * tests/conflicts.at (Unresolved SR Conflicts, Defaulted
+       Conflicted Reduction, %expect not enough, %expect too much,
+       %expect with reduce conflicts): Switch to Yacc-style conflict reports.
+       * tests/existing.at (GNU Cim Grammar): Likewise.
+       * tests/glr-regr1.at (Badly Collapsed GLR States): Likewise.
+
+       * src/complain.c (warn_at, warn, complain_at, complain, fatal_at,
+       fatal): Don't invoke fflush; it's not needed and it might even be
+       harmful for stdout, as stdout might not be open.
+       * src/reduce.c (reduce_print): Likewise.

+
+       Fix a bug where error locations were not being recorded correctly.
+       This problem was originally reported by Paul Hilfinger in
+       <http://mail.gnu.org/pipermail/bug-bison/2002-November/001901.html>.
+
+       * data/yacc.c (yyparse): New local var yylerrsp, to record the
+       top of the location stack's error locations.
+       (yyerrlab): Set it.  When discarding a token, push its location
+       onto yylerrsp so that we don't lose track of the error's end.
+       (yyerrlab1): Now is only the target of YYERROR, so that we can
+       properly record the location of the action that failed.  For GCC
+       2.93 and later, insert an __attribute__ ((__unused__)) to avoid
+       GCC warning about yyerrlab1 being unused if YYERROR is unused.
+       (yyerrlab2): New label, which yyerrlab now falls through to.
+       Compute the error's location by applying YYLLOC_DEFAULT to
+       the locations of all the symbols that went into the error.
+       * doc/bison.texinfo (Location Default Action): Mention that
+       YYLLOC_DEFAULT is also invoked for syntax errors.
+       * tests/actions.at (_AT_CHECK_PRINTER_AND_DESTRUCTOR):
+       Error locations include the locations of all the tokens that were
+       discarded, not just the last token.
+       
 2002-12-26  Paul Eggert  <eggert@twinsun.com>
 
+       * src/files.c: Include quote.h.
+       (compute_output_file_names): Warn if we detect conflicting
+       outputs to the same file.  This should catch the misunderstanding
+       exemplified by Debian Bug 165349, reported by Bruce Stephens..
+
+       * src/conflicts.c (conflicts_print): If the user specifies
+       "%expect N", report an error if there are any reduce/reduce
+       conflicts.  This is what the manual says should happen.
+       This fixes Debian bug 130890, reported by Anthony DeRobertis.
+       * tests/conflicts.at (%expect with reduce conflicts): New test.
+
        Don't use m4_include on relative file names, as it doesn't work as
        desired if there happens to be a file with that name under ".".
