+
+ * configure.ac (gcc_gxx_include_dir): Use $(libsubdir_to_prefix).
+ (gcc_tooldir): Likewise.
+ * configure: Regenerate.
+ * Makefile.in (libsubdir_to_prefix): New variable, based on the
+ old configure.ac gcc_tooldir setting.
+ (prefix_to_exec_prefix): New variable.
+ (DRIVER_DEFINES): Use $(libsubdir_to_prefix)$(prefix_to_exec_prefix)
+ rather than $(unlibsubdir)/../ to derive TOOLDIR_BASE_PREFIX.

* Makefile.in (OBJS-common): Add tree-ssa-alias-warnings.o.
