In the next release they'll be using sstream, with a fallback to
strstream when sstream is not available (eg. g++ 2.95).

We establish those options with independent tests.  In a few cases
-march can come out lower than -mcpu.  We've got a couple of cases
where gcc bugs are tickled by certain -march, and if the assembler is
too old an -march might be unusable altogether (eg. SSE2).
