The problem is not due to endian differences but compiler differences. I 
came across this problem when I have to combine two binary images while 
are compiled by different compilers: one by GCC, the other by SH 
proprietary compiler. However the bit-field's members are allocated from 
 the lower bit in GCC, while from higher bit in SH compiler.
