 * WORDS_ALIGNED : if defined, the host cpu can only make word aligned
28 28 
 * memory accesses.
29 29 
 *
30 
 * WORDS_BIGENDIAN : if defined, the host cpu is big endian and
30 
 * HOST_WORDS_BIGENDIAN : if defined, the host cpu is big endian and
31 31 
 * otherwise little endian.
32 32 
 *
33 33 
 * (TARGET_WORDS_ALIGNED : same for target cpu (not supported yet))
