10 *   12/11/96    helena      Creation.
11 *   02/27/97    aliu        Added typedefs for UClassID, int8, int16, int32,
12 *                           uint8, uint16, and uint32.
13 *   04/01/97    aliu        Added XP_CPLUSPLUS and modified to work under C as
14 *                            well as C++.
15 *                           Modified to use memcpy() for uprv_arrayCopy() fns.
16 *   04/14/97    aliu        Added TPlatformUtilities.
17 *   05/07/97    aliu        Added import/export specifiers (replacing the old
18 *                           broken EXT_CLASS).  Added version number for our
19 *                           code.  Cleaned up header.
20 *    6/20/97    helena      Java class name change.
21 *   08/11/98    stephen     UErrorCode changed from typedef to enum
22 *   08/12/98    erm         Changed T_ANALYTIC_PACKAGE_VERSION to 3
23 *   08/14/98    stephen     Added uprv_arrayCopy() for int8_t, int16_t, int32_t
24 *   12/09/98    jfitz       Added BUFFER_OVERFLOW_ERROR (bug 1100066)
