[PHPTAL] Verry little patch for phptal:cache

[Julien Fredon]

I've got an error with phptal:cache (php in stric mode) when the cache 
file doesn't exist :

filemtime() [function.filemtime 
<http://serveur:8166/function.filemtime>]: stat failed for 
templates_compilation/tpl_1_1_9f04e50e8bb416be9d5d0622ef9e2ece2.phpd7ba92263d785bb278522b594a8a8ae6


This little patch fix the problem for me.
