long longlong in libffi

Hi,
I have a bit a problem here, either I don't understand or something is 
wrong.
The box sitting on is a darwin6.3 machine. PPC 7410.
I run into problems when I play with long and longlong.
My system claims long as 4 byte and longlong as 8 bytes.
 From the config.status of libffi.
${ac_dA}SIZEOF_LONG${ac_dB}SIZEOF_LONG${ac_dC}4${ac_dD}
${ac_dA}SIZEOF_LONG_LONG${ac_dB}SIZEOF_LONG_LONG${ac_dC}8${ac_dD}
from fficonfig.h:
/* The number of bytes in a long. */
#define SIZEOF_LONG 4
/* The number of bytes in a long long. */
#define SIZEOF_LONG_LONG 8
from ffi.h
if SIZEOF_LONG == 4
#define UINT32 unsigned long
#define SINT32 long
#define ffi_type_ulong ffi_type_uint32
#define ffi_type_slong ffi_type_sint32
[snip]
#if SIZEOF_LONG == 8
#define UINT64 unsigned long
#define SINT64 long
#define ffi_type_ulong ffi_type_uint64
#define ffi_type_slong ffi_type_sint64
#else
#if SIZEOF_LONG_LONG == 8
#define UINT64 unsigned long long
#define SINT64 long long
#define ffi_type_ulong ffi_type_uint64
#define ffi_type_slong ffi_type_sint64
So in mycase the ffi_type_ulong gets uint64 and I can't distinguish 
between long and longlong except with uint32/64
What do I don't see here, is this the correct behavior?
Thanks,
Andreas
