-Win32API emulation
-
-MKXP-Z exposes an implementation of the Win32API module (called MiniFFI) by default.
-However, this alias is only actually useful on Windows. Therefore, we replace it
-with a pure-ruby version specifically implementing the most common imports.
-Real native libraries can still be accessed through MiniFII.new (e.g. in ports)
-
-Lambdas are used for implementations as they replicate Win32API's #call interface.
