[PATCH 04/18] comctl32: Extend TaskDialog, add simple callback and tests

[Fabian Maurer]

> How is this going to work with global variable?
Well, it's just a first implementation, I removed the global variables in later 
patchsets. But I'll rewrite it to store the taskdialog-data using dialog 
functions.

> For that please use msg.h from comctl32/tests.
I'd love to, but I'm not sure how this would work.
After all, the message lists for the taskdialogs use a different struct with 
additional values, like the return value it should give, and a sync value.
I agree that the current way isn't too elegant, how would you go about that?
