What happened to error details in stat

I remember that if error happened in stat- related functions, error message contained also system errno and message, like in following line: Warning: fileatime(): Stat failed for /tmp\lost+found (errno=2 - No such file or directory) in /home/rfresh/public_html/whosonline_form.php on line 93 But now it says only: Warning: filesize(): stat failed for non-existing-file in shell code on line 1 Why PHP doesn't report reason of stat failure anymore? It makes solving such problems much more difficult, as I don't know why stat failed. Note: first error message was copied from a forum post written in 2005. Jan Dolecek juzna.cz@gmail.com
