Win32 Project: How to add a .def file

[dee-u]

I am not able to find how can I add a .def file. Anyone who could pinpoint me where should I specify such file?

TIA

Upon more digging I've found out that I don't really need a Win32 dll to pass something to AutoIt so this case is rested although not resolved so I will not mark it as one.
