My LANG environment variable is "german". At the beginning of every page, I do `setLocale('LC_ALL', 'en_US')'. With those settings, float session variables are saved with `,' as decimal point, but loading seems to expect `.' so that I get values truncated to ints.

Example script:
<?
setLocale('LC_ALL', 'en_US');
session_start();
$x = & $HTTP_SESSION_VARS['x'];
if (!isset($x)) $x = 1;
$x *= '1.1';
print("$x<br>\n");
printf("<a href=\"%s\">go</a>\n", $HTTP_SERVER_VARS['PHP_SELF']);
// (link relies on transparent sid)
?>

The session file contains `x|d:1,1;', and the page always shows `1.1', since the loaded value becomes 1.
