Description:
------------
symlink() fails to create a relative link if the working dir is not the same as where the link is going (works correctly on Linux). Relative targets should be resolved from the dir the link will be. For now, my workaround is calling mklink through shell_exec.

Test script:
---------------
<?php
file_put_contents("test.txt", time());

mkdir("a");

echo "symlink(): ";
symlink("..\\test.txt", "a\\1.txt") && print("success\n");

echo "\nmklink: ".shell_exec("mklink a\\2.txt ..\\test.txt");

echo "\nchdir(), symlink(): ";
chdir("a");
symlink("..\\test.txt", "3.txt") && print("success\n");


Actual result:
--------------
C:\php-test>php a.php
symlink(): PHP Warning:  symlink(): Could not fetch file information(error 2) in C:\php-test\a.php on line 7

Warning: symlink(): Could not fetch file information(error 2) in C:\php-test\a.php on line 7

mklink: symbolic link created for a\2.txt <<===>> ..\test.txt

chdir(), symlink(): success
