While it may work, we don't fully support using MSVC for developing
server-side extensions. Not sure if it's related to your problem, but
it's quite possible. You will need to get the MingW toolset to developer
server-side. (You can still use the VS IDE if you want to, of course,
but you need to use the gcc compiler from MingW).
