Description:
------------
Hi,

rename ( 'file1', 'file2' ); 

behaviour at linux:

If there is a 'file2', the file2 will be overwritten by file1.

at windows xp:
If there is a 'file2', a warning is given and the file2 isn't overwritten with file1.

Reproduce code:
---------------
rename ( 'file1', 'file2' ); 



Expected result:
----------------
I would expect, that rename() works with the same behaviour at all operating systems.

So, please overwrite existing files or give a warning at all os.

Actual result:
--------------
rename()
at linux, existing files will be overwritten, at winxp, the rename-process fails, a php-warning is given.
