@pajoye I am using VC9 NTS version on Windows.

It does work, it gives you the target of the given link.
The only difference is an OS specific implementation where all links are
resolved.
I suppose you use a TS php on windows and a NTS on linux, right?

Description:
------------
When creating a symlink in Windows to an absolute path with a lower case drive
letter, PHP will not resolve the canonicalized absolute pathname (realpath)
correctly.
This is obvious when you have nested symlinks.
When you run realpath of a nested symlink it returns the next symlink it links
to, rather than the top absolute pathname.
On Linux it works correctly.
One work around that can be used is:
$link = 'f:\link3';
do {
$link = realpath($link);
} while (realpath($link) !== false && $link !== realpath($link));
Test script:
---------------
Windows test:
F:\>mkdir target
F:\>mklink /D link1 f:\target
F:\>mklink /D link2 f:\link1
F:\>mklink /D link3 f:\link2
F:\>php -r "var_dump(realpath('link3'));"
Linux test:
$ mkdir target
$ ln -s target link1
$ ln -s link1 link2
$ ln -s link2 link3
$ php -r "var_dump(realpath('link3'));"
Expected result:
----------------
Windows test:
string(9) "F:\target"
Linux test:
string(12) "/root/target"
Actual result:
--------------
Windows test:
string(9) "f:\\link2"
Linux test:
string(12) "/root/target"
