> The [{{22.locale.num.put.cpp}}|http://svn.apache.org/repos/asf/stdcxx/trunk/tests/localization/22.locale.num.put.cpp] fails 4 assertions with the head of trunk (see below). The test passes at 100% with 4.2.0. I reduced the failures to the following test case:
> {noformat}
> $ cat t.cpp && gmake t && ./t 
> #include <cassert>
> #include <cstdio>
> #include <math.h>
> #include <sstream>
> int main ()
> {
>     const long double x = 1.0e+4932L;
>     assert (isnormal (x));
>     std::ostringstream strm;
>     strm << x;
>     char buf [40];
>     std::sprintf (buf, "%Lg", x);
>     if (strm.str () == buf)
>         return 0;
>     std::printf ("%s != %s\n", strm.str ().c_str (), buf);
>     assert (0);
