There's a more nuanced possibility though:  Use the FFI C-parser to
_automatically_ produce classical C bindings in the pure Lua case (but
use FFI when on Luajit).

This restricts you compared to pure FFI (in the pure-Lua case, the above
build process must be at "compile/install time", not at runtime like
FFI), but for many common scenarios it could give much of the
convenience of FFI while still remaining portable.
