LJIT2Win32
A collection of LuaJIT FFI interfaces and utilities for programming in the Windows environment.
If you are interested in LuaJIT bindings for Win32, I strongly encourage you to take a look at TINN: http://github.com/wiladams/TINN
There are a lot more bindings, to a much broader set of Windows routines, and they're kept more up to date.
Even more recent, and more faithful to Win32 API is lj2win32
