Comment (by pbristow):

 Replying to [comment:7 pbristow]:

 I have now written a much larger collection of tests (though there are an
 almost infinite number of possible combinations of ostream options like
 precision, width, letf right, internal, showpos showpoint :-(

 And committed a revised version (using code from KR Walker) that passes on
 MSVC 10 these tests with the signed_zero flag set (and also handles inf
 and nan as before).

 I am not entirely convinced that there is really a need for a signed_zero
 flag at all.

 Are there really any platforms/libraries still out there that do not
 output negative zero correctly as -0?

 Feedback welcome.
