Last time I checked, bit fields in structs are not guaranteed to be 
interpreted in the same way for various architectures. You can get it to 
do "the right thing" for a particular architecture, but not necesserilly 
outside of that scope.

So, it's a two-edged sword.

Bit-masks, shift constants etc. is unfortunatly the only way to do 
portable stuff to match with protocols and hardware stuff.
