00018 *   This file defines basic types and constants for ICU to be
00019 *   platform-independent. umachine.h and utf.h are included into
00020 *   utypes.h to provide all the general definitions for ICU.
00021 *   All of these definitions used to be in utypes.h before
00022 *   the UTF-handling macros made this unmaintainable.
