Thanks for this Paolo. I think that there are probably problems with the 
current testcases, so beware.

Thanks.

(gdb) p wcmp
$2 = 52

And then in Paolo's test case

wcmp = __wcscoll_l(__one, __two, loc);
(gdb) p wcmp
$1 = 20

Hmm. Me too, but I don't have the same results as you either.

%rpm -q glibc
glibc-2.2.4-19.3

Right. They're XFAILED. If they pass, it's a bonus. On linux, they should 
pass.
