if copy('file','dest') is called, and the 'file' is a 0-length file, it will fail.  This causes pear install PhpDocumentor to fail on windows.

To test, create an empty file "emptyfile.php" and a non-empty file "nonemptyfile.php" in the same directory as this script, and run it:

<?php
var_dump(copy('emptyfile.php','newfile.php')); // bool(false)
var_dump(copy('nonemptyfile.php','newfile.php')); //bool(true)
?>

This problem seems to occur on the platforms which doesn't have mmap function.

This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.

The fix will go in the next CVS snapshot that will be available in about 5 hours.
