No vc11 folder generated.

I'm trying to build php 5.5+ from source in windows 8, i followed the steps given in http://wiki.php.net/internals/windows/stepbystepbuild, i used php-sdk version- "php-sdk-binary-tools-20110512" to generate the folder  "phpdev" under the directory " C:\php-sdk\" ,the problem is i don't see any "vc11" folder under the directory
"C:\php-sdk\phpdev\" ,although "vc6","vc8" and "vc9" folder are automatically generated, is something wrong with my php-sdk version or is it something else. Help.
