-/**
- * Base type definitions and aliases.
- *
- * This module doesn't provide aliases for all types used by Windows, but only
- * for types that can vary on different platforms. For example there is no
- * need to define `INT32` alias for D, since $(D_KEYWORD int) is always a
- * 32-bit signed integer. But `int` and its Windows alias `INT` is not the
- * same on all platforms in C, so its size can be something differen than
- * 32 bit, therefore an $(D_PSYMBOL INT) alias is available in this module.
- * $(D_PARAM TCHAR) can be a $(D_KEYWORD char) if Unicode isn't supported or
- * $(D_KEYWORD wchar) if Unicode is supported, so $(D_PSYMBOL TCHAR) is
- * defined here.
- * Also aliases for specific types like $(D_PSYMBOL SOCKET) are defined here.
