+ * 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.
