}
/* You also need a .def file included in your "Source Files" containing
some info on the DLL. Mine looks like:
LIBRARY testmirc
DESCRIPTION "Example of using a DLL with mIRC"
EXPORTS
funcname
That's all, make sure you name it something.def and add it properly, 
after that, it should compile fine and give you a .dll to work with.
