10 *
11 * Date Name Description
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.
29 * 05/05/99 stephen Changed to use <inttypes.h>
30 * 12/07/99 helena Moved copyright notice string from ucnv_bld.h here.
