Actually, the above will not even compile under G++. The docs say to append
__attribute__ ((packed)) to the end of every field, not the structure
declaration. However, your approach works with GNU C, though it is not
documented. GNU C++ does not accept it. I like your approach ( no extra
typing ) and I think G++ does not understand it due to a bug. I've reported
this to gcc bug list.
