The following php code gives a parse error at the 'else:'

<?php
if(1==1):
        echo "ok so far<p>";
        if(1==1) echo "error here!";
else:
        echo "Not possible";
endif;
?>

It looks like php thinks the 'else:' is part of the second 
if construct; the following code works:

<?php
if(1==1):
        echo "ok so far<p>";
        if(1==1) echo "error here!";
        echo "void";
else:
        echo "Not possible";
endif;
?>

Tested with 4.0.3pl1, 4.0.4RC3 and 3.0.18 on debian woody and potato.
