00016 *   This file defines basic types and constants for ICU to be
00017 *   platform-independent. umachine.h and utf.h are included into
00018 *   utypes.h to provide all the general definitions for ICU.
00019 *   All of these definitions used to be in utypes.h before
00020 *   the UTF-handling macros made this unmaintainable.
