+
+       In the grammar scanner, STRING_FINISH unclosed constructs and return
+       them to the parser in order to improve error messages.
+       * src/scan-gram.l (SC_ESCAPED_STRING, SC_ESCAPED_CHARACTER,
+       SC_BRACED_CODE, SC_PROLOGUE): Implement.
+       * tests/input.at (Unclosed constructs): New test case.
+       * tests/regression.at (Invalid inputs): Update now that unclosed %{ is
+       seen.
+
+       * src/scan-gram.h, src/scan-gram.l (gram_last_braced_code_loc): Remove
+       unused global.

+
+       Handle string aliases for character tokens correctly.
+       * src/symtab.c (symbol_user_token_number_set): If the token has an
+       alias, check and set its alias's user token number instead of its own,
+       which is set to indicate the alias.  Previously, every occurrence of
+       the character token in the grammar overwrote that alias indicator with
+       the character code.
+       * tests/input.at (String aliases for character tokens): New test.
+
+2006-08-12  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+       * src/parse-gram.y: Add `%expect 0' so we don't overlook conflicts.
+
+2006-08-11  Paul Eggert  <eggert@cs.ucla.edu>
+
+       * bootstrap: Put in need-ngettext argument to AM_GNU_GETTEXT,
+       to prevent failures when building on older platforms.
+       Check for autopoint failure.
+       Set XGETTEXT_OPTIONS to values that check for C format strings,
+       so that translators are warned about them (this also helps
+       prevent core dumps).
+
+       * lib/subpipe.c (create_subpipe): Use new gnulib pipe_safer
+       function, since it simplifies our code a bit.
+
+       * configure.ac (AC_ARG_ENABLE): Use -Wextra -Wno-sign-compare
+       rather than -W, so we don't get bogus warnings about sign comparisons.
+       Add -Wpointer-arith, since that warning is useful (it reports code
+       that does not conform to C89 and that some compilers reject).
+       * data/c.m4, data/glr.c, data/lalr1.cc, data/yacc.c: Undo latest change,
+       since it's no longer needed.
+
+2006-08-10  Joel E. Denny  <jdenny@ces.clemson.edu>
+
+       Clean up scanners a bit.
+       * src/flex-scanner.h (FLEX_NO_OBSTACK): New macro that blocks obstack
+       definitions so gcc won't warn when obstack_for_string is unused.
+       * src/scan-code.l: config.h and system.h are already #include'd by
+       scan-code-c.c, so get rid of them here.
+       * src/scan-gram.l: Likewise.
+       * src/scan-skel.l: Likewise, and use flex-scanner.h without obstack
+       definitions rather than duplicating the rest of it.
+       * src/scan-gram-c.c, scan-skel-c.c: #include "system.h".

        Suppress signed/unsigned comparison warnings for yycheck.
