As you guessed, that would be a bad assumption; we shouldn't assume
functionality beyond that required from the ISO C++ runtime, as
augmented by extensions in libstdc++, except with appropriate target
markers or #ifdefs.  (We try to make the C++ compiler testsuite depend
on as little library functionality as possible, in general.)

Yes, that's a good change.

Yes, thanks.
