//
//	Macros to support allocation of variables and structures
//	that are guaranteed to be aligned on a 16-byte boundary.
//	Note that ONLY the first variable in the structure is
//	guaranteed to align on a 16-byte boundary; the alignment
//	of the remaining elements follows the standard packing
//	rules for c/c++ structure members.
