12 *   12/11/96    helena      Creation.
13 *   02/27/97    aliu        Added typedefs for UClassID, int8, int16, int32,
14 *                           uint8, uint16, and uint32.
15 *   04/01/97    aliu        Added XP_CPLUSPLUS and modified to work under C as
16 *                            well as C++.
17 *                           Modified to use memcpy() for uprv_arrayCopy() fns.
