/*
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
