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.
18 *   04/14/97    aliu        Added TPlatformUtilities.
19 *   05/07/97    aliu        Added import/export specifiers (replacing the old
20 *                           broken EXT_CLASS).  Added version number for our
21 *                           code.  Cleaned up header.
22 *    6/20/97    helena      Java class name change.
23 *   08/11/98    stephen     UErrorCode changed from typedef to enum
24 *   08/12/98    erm         Changed T_ANALYTIC_PACKAGE_VERSION to 3
25 *   08/14/98    stephen     Added uprv_arrayCopy() for int8_t, int16_t, int32_t
26 *   12/09/98    jfitz       Added BUFFER_OVERFLOW_ERROR (bug 1100066)
27 *   04/20/99    stephen     Cleaned up & reworked for autoconf.
28 *                           Renamed to utypes.h.
