Author: Jason Merrill <jason@redhat.com>
Date:   Wed Jul 13 14:23:20 2011 -0400

    Also test -std=c++0x mode with 'make check-c++' at top level
    	* Makefile.in (check-gcc-c++0x): New.
    	(check-c++): Depend on it.
    gcc/
    	* Makefile.in ($(lang_checks_parallelized)): Allow --tool_opts.
    gcc/cp/
    	* Make-lang.in (check-c++0x): New.
    gcc/testsuite/
    	* lib/g++.exp (${tool}_option_help, ${tool}_option_proc): Remove.
    	* lib/lto.exp (lto_prune_warns): Prune warning about -std=c++0x
    	when compiling C files.
