FFI callbacks with structs as arguments.

I have a Lua function that I want to use as a callback from C. The C type
of the callback includes a struct as argument.
When I try to create this callback in LuaJIT, I get an error. For instance:
ffi = require("ffi")
ffi.cdef("typedef struct {} A;")
ffi.cdef("typedef (*fn)(A);")
function myfn(a)
end
result = ffi.cast("fn",myfn) -- cannot convert 'function' to 'void (*)()'
Is this functionality not currently supported?
Thanks,
Zach
