Problem compiling a custom extension

I am able to compile PHP, but I am trying to create an extension ( following zend's hello world tutorial ) and the configure step will not recognize my enable command. I'm working with: PHP5.1 and have tried both win2k3/vs.net and winxp/vsc++6 with the exact same results. My file structure looks like this: c:\phpdev\php5.1\ext\hello\hello.h c:\phpdev\php5.1\ext\hello\hello.c c:\phpdev\php5.1\ext\hello\config.m4 According to the PHP documentation, I should be able to run the following command: cscript /nologo configure.js --enable-hello=shared I have also tried --enable-hello=yes, and --enable-hello= c:\phpdev\php5.1\ext\hello,shared All attempts result in the same configuration error: "C:\phpdev\php5.1>cscript /nologo configure.js --enable-hello=shared Unknown option --enable-hello; please try configure.js --help for a list of valid options" When I run configure.js --help, I do not see --enable-hello as an option. Is there a step I'm missing that will allow my configuration to recognize my new extension so I can compile it? Thanks in advance
