COM works fine with gcc/w32api. The vtable layout was fixed some years 
ago. Just for directx you'd need some stubs which are available elsewhere.

$ grep CoInitialize /usr/include/w32api/*
$ grep CTaskScheduler /usr/include/w32api/*
$ grep CTaskScheduler /usr/include/mingw/*

This CLSID CLSID_CTaskScheduler is not in w32api and not in mingw.
So you have to find the raw CLSID string. I didn't find it in 
oleview.exe or the registry, so you to find the CLSID elsewhere. in the 
official headers it should be somewhere.

Good idea btw. No need for another service, while we already have a 
scheduler.

Better avoid AFX templates and use easier STL templates instead.
