//
//	COMMON DATA TYPES
//
//	As much as possible, programs should use natural data types (eg. int) to
//	allow compiler optimizations to kick in.  When specific data widths are
//	required, then the following types should be used.  Note that on some
//	platforms, like PalmOS, an int is ONLY 16-BITS, therefore, int must be
//	used carefully, and that all int expresions will not be promoted to longs.
//
//	Please do not declare HAL-specific datatypes here, put them in hal.h!
