About a module ffi, which is required in a regression test of luaossl

[Lemures Lemniscati <lemures.lemniscati@...>]

Hi!

I'm trying to build and test luaossl from source [1] on cygwin.

But when I ran regress/104-interposition-discarded.lua, it failed with a
message:

> regress: module ffi required

I would like to know which 'ffi' module is required.
Is it luaffi [2] ? 

Or, shuold I ask in the upstream [1], as an issue?
