It's not that bad (though of course it's not trivial either). Once
you prune the full C expression grammar to only what the
preprocessor supports, it's just a bit more complicated than
parsing Lua expressions. Well, except for sizeof()...
Although does it make sense to expect a Lua FFI package to read
implementation C header files? They are clunky and often depend on
lots of little bits. Much better to have a tool to massage them and
extract exactly what one wants, and include that. Such a tool could
start out by using the standalone C preprocessor as a first step.
A full-featured C preprocessor would be very convenient while a
kind of binary chunk equivalent for FFI specifications would be
