+
+        * builtins.c (expand_builtin_setjmp): Use emit_jump to jump around
+        the != 0 case, which ensures pending stack adjustments are flushed.
+
+2003-08-30  Zack Weinberg  <zack@codesourcery.com>
+
+       * configure.frag: Delete file.
+       * configure.in: Rename the substitution variables
+       dep_host_xmake_file and dep_tmake_file to xmake_file and
+       tmake_file respectively.  Do not expand $srcdir in the
+       value of these; leave that for Make.  Introduce a new
+       substitution varaible, all_lang_makefrags, which lists
+       subdirectory Make-lang.in files; exclude these from
+       all_lang_makefiles, which is now only for subdirectory
+       outputs.  Do not invoke configure.frag.  Do not set nor
+       AC_SUBST_FILE target_overrides, host_overrides, or
+       language_fragments. Create build subdirectories in
+       config.status extra commands.
+       * configure: Regenerate.
+       * Makefile.in: Update substitutions to match changes to
+       configure.  Use include directives instead of @-insertions
+       to read in host, target, and language fragments.
+       (Makefile rule): Do not invoke configure.frag.  Do not copy
+       config.status to config.run before executing it.  Set
+       CONFIG_HEADERS and CONFIG_FILES so that only Makefile gets
+       regenerated.
+       (cstamp-h rule): Set CONFIG_FILES as well as CONFIG_HEADERS.

+       * c-typeck.c (same_translation_unit_p): New function.
+       (comptypes): Use it instead of flags parameter to identify
+       structure types from different translation units.
+       * c-decl.c (duplicate_decls): Always call comptypes with
+       COMPTYPE_STRICT flags argument.
+       (c_reset_state): Set BLOCK_SUPERCONTEXT of the block formed
+       to file_scope_decl.

+       (finish_struct): Look at C_TYPE_INCOMPLETE_VARS for variables
+       to complete, not at current_scope->incomplete.  All such
+       variables do need completion.
