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.
