How to specify compiler options on Win32

Hi, Using the guide on the Zend site (http://www.zend.com/manual/install.windows.php#install.windows.build) I have successfully compiled and built the Win32 version of PHP using Visual C++. For now I am building the CLI version - and it works just great, but I have what is probably a very basic question - how do you add the compile time options when building it? For example I want to build the CLI version with --enable-memory-limit so I can use the memory_get_usage() function - but I am simply not sure where to specify this before building the project. I'm guessing it lurks somewhere in the Project Settings for php4ts_cli?
