In pdlua I used some preprocessor magic similar to this, not sure how it 
compares to the zexy/iemlibs magic but I guess it's roughly the same:

/* use new garray support that is 64-bit safe */
#  define PDLUA_ARRAYGRAB garray_getfloatwords
#  define PDLUA_ARRAYTYPE t_word
#  define PDLUA_ARRAYELEM(arr,idx) ((arr)[(idx)].w_float)
# else
/* use old garray support, not 64-bit safe */
#  define PDLUA_ARRAYGRAB garray_getfloatarray
#  define PDLUA_ARRAYTYPE t_float
#  define PDLUA_ARRAYELEM(arr,idx) ((arr)[(idx)])
# endif

then use the macros instead of direct array access, still needs some 
work to change all array-related lines as IOhannes says...

I'm not even sure this is correct, works for me on my 32bit system.
