8*
9* Date Name Description
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)
25* 04/20/99 stephen Cleaned up & reworked for autoconf.
26* Renamed to utypes.h.
27* 05/05/99 stephen Changed to use <inttypes.h>
28* 12/07/99 helena Moved copyright notice string from ucnv_bld.h here.
