Per your and my changes a few days ago, we've already got libstdc++ covered, with the sole exception of: PASS: 27_io/basic_ostream/inserters_arithmetic/pod/23875.cc (test for e= xcess errors) [-PASS:-]{+FAIL:+} 27_io/basic_ostream/inserters_arithmetic/pod/23875.c= c execution test terminate called after throwing an instance of 'std::bad_cast' what(): std::bad_cast (Low priority for me.) Not having heard anything contrary regarding the compiler side of things, I've now been working on that, see below. > We already have a handful of tests that use #if __cpp_exceptions to make > those parts conditional on exception support. Yes, that's an option not for all but certainly for some test cases. (I'm not looking into that now -- but this may in fact be a good beginner-level task, will add to ). >> Otherwise, a number of test cases need DejaGnu directives >> conditionalized on 'target exceptions_enabled'.

I still like the idea, but yes, I've mentally put it on file "for later" (ha, ha, ha...) -- it doesn't seem obvious to implement.
