Description:
------------
realpath() doesn't resolve symlink and returns the link file name when
input path is a link path.

As per the documentation at
http://in.php.net/manual/en/function.realpath.php, The resulting path
will have no symbolic link, '/./' or '/../' components.

Applicable to php5.2.4 only on MacOS X.

Please check testcase symlink_link_linkinfo_is_link_variation6.phpt.

Reproduce code:
---------------
<?php
$file_path = dirname(__FILE__);
$filename = "$file_path/file.tmp";
$linkname = "$file_path/link.tmp";

$fp = fopen($filename, "w");
fclose($fp);

symlink($filename, $linkname); 
var_dump( realpath($linkname) );

unlink($linkname);
unlink($filename);
?>

Expected result:
----------------
string(%d) "%s/file.tmp"

Actual result:
--------------
string(%d) "%s/link.tmp"

The reference to testcase symlink_link_linkinfo_is_link_variation6.phpt
is wrong. The write testcases to check are :
ext/standard/tests/file/readlink_realpath_basic1.phpt
ext/standard/tests/file/readlink_realpath_variation1.phpt
ext/standard/tests/file/readlink_realpath_variation2.phpt

The similar failure is also noticed on FreeBSD.

I'm guessing this should be fixed in PHP_5_3 and HEAD by the commit by
Dmitry?

Hi Jani,

I do not MacOSX/FreeBSD system to verify this. If you know someone who
has, pls request for verfication. 

PS: When i raised this defect ,i used test run report sent by others
over the php-qa list.
