If you are trying to use some standard Microsoft component, it may be
already defined in w32api headers (oleauto.h, oleidl.h) etc. For inproc
server it should be enough - just include necessary header. You can even
declare third-party interface yourself using DECLARE_INTERFACE_ macro (see
oleauto.h for examples). But in the more compex case you will need .idl
definition and Microsoft midl compiler which is non-free and does not
support gcc out of the box. #import directive is also not supported. So you
probably will have to use other compiler.

Hope to hear from you soon,
