I'm finding that all the new g++.dg/ext/is_*.C testcases added by this patch 
series are failing due
to the "#include <testsuite_tr1.h>".  If that is supposed to refer to the file 
of that name in the libstdc++ testcase, there's no gcc option being passed to 
add that location to the include search path.  That .h file includes other 
header files from the libstdc++ testsuite so just copying it into the same 
directory as the new g++ tests doesn't work.  Can you fix this, somehow?

Target is nios2-elf, if that matters.
