 Yes, configuring --enable-clocale=generic, something
 wrong happens:
 
 paolo:~> a.out
 12/11/02
 12/11/00paolo:~>
 
 The dates are unexpectedly different!
 
 Investigating further...
 
 Ciao,

    He's on W2k, using cygwin, so you'll have to use the generic locale model.

State-Changed-Why:
    What are you actually getting at run time?
    If, paying attention to the warning ;), I modify line #8
    of your testcase from
      tm* lt = localtime(&time(0));
    to something like
      time_t tt = time(0);
      tm* lt = localtime(&tt);
    The date is correctly printed twice on my i686-pc-linux-gnu
    box.
