Description:
------------
localeconv() function returns the wrong values for int_frac_digits and frac_digits. they should be "2" and not "0" (which was correct in the time of the Lira)


Reproduce code:
---------------
<?php
setlocale(LC_ALL, it_IT);
var_dump(localeconv());


Expected result:
----------------
array(18) {
  ["decimal_point"]=>
  string(1) "."
<snip>
  ["int_frac_digits"]=>
  int(2)
  ["frac_digits"]=>
  int(2)
<snip>
  ["mon_grouping"]=>
  array(2) {
    [0]=>
    int(3)
    [1]=>
    int(3)
  }
}

Actual result:
--------------
array(18) {
  ["decimal_point"]=>
  string(1) "."
<snip>
  ["int_frac_digits"]=>
  int(0)
  ["frac_digits"]=>
  int(0)
<snip>
  ["mon_grouping"]=>
  array(2) {
    [0]=>
    int(3)
    [1]=>
    int(3)
  }
}
