I'm guessing your compiler for whatever architecture you are using does not 
support packed structures.
My 16-bit M16C arch compiler does not, and all I had to do was to change 
the defines related to the packed structures in cc.h to not use packed 
structures.

before:
#define PACK_STRUCT_FIELD(x) x __attribute__((packed))
#define PACK_STRUCT_STRUCT __attribute__((packed))
#define PACK_STRUCT_BEGIN
#define PACK_STRUCT_END

after (no pack):
#define PACK_STRUCT_FIELD(x) x
#define PACK_STRUCT_STRUCT
#define PACK_STRUCT_BEGIN
#define PACK_STRUCT_END
