After commit 3701d49 'error_resilience: remove avpriv_atomic usage'
we have included windows.h in much more files and we should
avoid conflicts with defines/function declarations.

Does Rect instead of ff_Rectangle work too ?

The ff_ is a bit confusng as its outside how we name structs
(struct identifers are capitalized)

Yes, Rect works. I've checked also MSS2Rectangle -- works too and in mss2.c there is for example
typedef struct MSS2Context

Should I resent this patch with Rect or MSS2Rectangle?
