Error "cannot redeclare class Auth in php/pear/Auth.php"

[maspai]

I use XAMPP both in Linux and Windows (ver 1.8.3).
Opening in Windows a PHP website I write in Linux results error as in topic title. I create a class named Auth used in my program, and no error in Linux.
I tried uninstall and install older version of Windows XAMPP, 1.8.1. Same error. Also after I change name of the class to auth.
Thanks for help.

Either delete pear Package (what i do not recommend) or rename your own class from Auth to a different name. Auth is already used by pear, maybe pear is not installed on your Linux version or comes with a different release.

I did change the class name, from Auth to auth, as I already said in first post. But same error appears. Maybe I'll retry it, restart XAMPP in the Windows box. Thanks anyway.

PHP Class Names are NOT case sensitiv (so changing from upper to lower does not change anything).
