This is a different issue. Anyway, concentrating on basic_streambuf<>::xsputn
(I don't think we should fiddle that late with the deprecated strstream), note
that __len is smaller than __buf_len, and typically __buf_len ~= 8192. Thus I
would consider the problem rather minor. Anyway, I'm in favor of something like
your first hunk, with a comment before about streamsize == ptrdiff_t, and using
__gnu_cxx::__numeric_traits<int>::__max instead (thus avoiding bringing in the
whole <limits>).
Probably we used to be not careful enough in xsputn because streamsize is (was)
normally 32 bits on 32-bit machines (being ptrdiff_t).
