Bitfields?

Hi,
http://luajit.org/ext_ffi_semantics.html seems to suggest that LuaJIT supports
bitfields in ffi cdefs. However:
$ luajit21 -e 'require"ffi".cdef"struct test { long d:8; };"'
luajit21: (command line):1: invalid value near ':'
stack traceback:
[C]: in function 'cdef'
(command line):1: in main chunk
[C]: at 0x0100000bb0
Since I’m a bit rusty on bitfields, I checked my bitfield syntax with:
$ echo "struct test { long d:8; };" | clang -Wall -Wextra -c -xc -
which seems to work. Anyone either know more about LuaJIT’s bitfield support
or able to point out my obvious mistake?
Thanks,
Geoff
