---------------------------------------
The following still fails with the first patch:
{noformat}
$ cat ../../tests/localization/t.cpp; nice make t.cpp && ./t af_ZA.utf8; echo $?
#include <iostream>
#include <locale>
#include <string>
int
main (int argc, char** argv)
{
std::locale loc (argv [1]);
const std::collate< char >& fac =
std::use_facet< std::collate< char > > (loc);
char const buf [] = "a\0\0b";
std::string s = fac.transform (buf, buf + sizeof buf - 1);
size_t i = 0;
for (; i < s.size () && 0 == s [i]; ++i) ;
return !(i == 2);
