+This file must be included only to one C++ file in project before
+declarations of COM interfaces with DEFINE_GUID macro.
+
+Each GUID must be initialized exactly once in project.
+There are two different versions of the DEFINE_GUID macro in guiddef.h (MyGuidDef.h):
+  - if INITGUID is not defined:  DEFINE_GUID declares an external reference to the symbol name.
+  - if INITGUID is     defined:  DEFINE_GUID initializes the symbol name to the value of the GUID.
+
+Also we need IID_IUnknown that is initialized in some file for linking:
+  MSVC:  by default the linker uses some lib file that contains IID_IUnknown
+  MinGW: add -luuid switch for linker
+  WinCE: we define IID_IUnknown in this file
+  Other: we define IID_IUnknown in this file
