Help! ERROR LINK 2005 raised when create PHP extension DLL using STL in VC++2005!

I created a VC++2005 PHP extension DLL project following the link
"Creating a PHP 5 Extension with Visual C++ 2005" :http://
blog.slickedit.com/?p=128#comment-161

Compiling and link are OK when just not include STL. But When I
included STL header files and used STL object, I got ERROR LINK 2005
as follows. Any one can give me a hint? Thanks.
