First, we would need a static php.lib (doable, but so far not supported by the build system). Then, apparently, we would need to get rid of the __declspec(dllimport) at least for the functions we want to mock when building php.lib; to do that it might be necessary to use modified copies of the WindowSDK headers. Ugly. And then we might need an own unit test suite for Windows; at least as is, test_network.c makes quite some assumptions regarding code paths (e.g. that poll(2) is called), which are not portable. I'm not sure it's worth pursuing this for other platforms than Linux. Christoph
