* IMPORTANT:
* All structures below are designed to be the same size when compiled for 32
* and/or 64 bit architectures, i.e. there should be no compiler inserted
* padding. This is achieved by sticking to the following rules:
* 1) only use fixed width types
* 2) always naturally align fields by arranging them appropriately and by using
* padding fields when necessary
*
* These rules should _always_ be followed when modifying or adding new
* structures to this file.
