Description:
------------
when compiled with "--with-curlwrappers", php 5.1.4 fails to fail an fopen request when you provide it with a uri containing an invalid host name, when recompiled without "--with-curlwrappers", it fails as expected...

this results in php invalidly returing a valid fopen resource even if the remote host is unreachable (e.g. because of a network problem)


Reproduce code:
---------------
<?

$file = fopen('http://non.existent.host', 'rb');

print_r($file);
echo "\n";

?>


Expected result:
----------------
it should display a warning (if enabled) and return "false" in $file

Actual result:
--------------
with "--with-curlwrappers", it returns "Resource id #5" in $file and doesn't warn of an error whatsoever
