Please try using this CVS snapshot:

  http://snaps.php.net/php4-STABLE-latest.tar.gz
 
For Windows:
 
  http://snaps.php.net/win32/php4-win32-STABLE-latest.zip

It works fine for me.
Please check it by CVS snapshot of PHP 4.4.

Code:
<?php
$name = "user/1/viewuser/1/edit";
if (ereg("[^\x80-\xF7 [:alnum:]@_.-]", $name)) {
  print "The username contains an illegal character.\n";
 } else {
  print "ok.\n";
 }
?>

Result in PHP 4.4.2RC2-dev (Linux FedoraCore4):
 The username contains an illegal character.

Moriyoshi, I guess you need to backport something..?
