That's expected.  I mentioned when I posted the patches that the implementation
is for little endian machines.  I don't have access to any big endian machines
and therefore didn't even try to make it work.

It might be sufficient, at end of _M_gen_rand, to swap the order of the four
32-bit words in a 128-bit word.  I never tested this, someone else will have to
do this.
