fix v1.0

It's mostly due to using MS-style inline assembly. I could add ifdefed GCC assembly, but I think it's cleaner to use the existing solution for win64 and call RtlCaptureContext.

I've also changed case in windows.h include to fix cross compiling on case sensitive OSes.

Thanks for the patch. Unfortunately, I just found out on #developers that we still nominally support Windows 2000, where RtlCaptureContext is unavailable. Is there some other way to do this?

Thanks for quick review. I've attached two versions of the fix that will keep support for win2k. The first version is just a port of existing assembly code to GCC. The second version is my previous approach, ifdefed so that MSC builds will still use assembly code. I think it's fine to not support win2k in mingw builds (I'd expect it to be already broken). Also this way, once we'll drop win2k support, we can just remove _MSC_VER ifdef and use the new code for MSC as well. I will the choice for you.
