Description:
------------
I'm trying to pass an external link to the file() function, but it returns a weird error message in portuguese.
Assuming that I live in Brazil, the message in portuguese is not the problem. What I don't understand is that the code was working, then suddenly it started to raise the error message.

Reproduce code:
---------------
<?php
  $aOrigem = file('http://rss.terra.com.br/0,,EI4795,00.xml');
?>

Expected result:
----------------
The lines of the file 0,,EI4795,00.xml should be passed as an array to $aOrigem.

Actual result:
--------------
I received this error message:
Warning: file(http://rss.terra.com.br/0,,EI4795,00.xml) [function.file]: failed to open stream: Falha de uma chamada ao sistema que n?o deveria falhar nunca. in D:\WebRoot\atualiza_xml.php on line 2

Translating the error message to english:
"Fail in a system call which should never have failed."

I don't believe this is a coding issue, since the file is only 1 line long, and this code was working about 2 hours ago.
