I tried out this stuff on irix6.5 against the trunk.  I had to add
this minor patch for it to work there as opposed to 3.3-pre:

Bootstrap went ok, however there were a couple of regressions in the
c-torture testsuite:

These tests both manipulate long doubles.

Also the original test 27_io/ostream_inserter_arith still fails.
However it looks as if it's in a different place, I'll check further
and provide details.
