Module Name:

    chartype.h

Abstract:

    Declares macros and types for the multi-byte and Unicode
    character environment that the Win9x upgrade code requires.
    The following macros are defined:

    - Make sure UNICODE is defined if _UNICODE is defined
    - Make the type MBCHAR that holds both bytes of a multi-byte char
    - Make CHARTYPE point to wint_t for UNICODE and MBCHAR for not
      UNICODE
