Creating extensions problem

Hello, I am using PHP-4.1.2 on WinNT. I need to create php-extension dll of my own. I downloaded the source and build php4ts.dll and php4ts.lib, but when i try to create the php.exe, it fails giving error while linking. I also included the lib and include directories from http://www.php.net/extra/win32build.zip. So I downloaded WIN32 binaries for this version. MSVC builds my extension dll properly, but when i try to load i get error indicating that its not a valid php extension dll. For testing, i just used sample code provided with php-manual for an extension dll. If anyone, has successfully build and used any extension dll, please give me some inputs on that.
