Recent Fedora complains while compiling ui/sdl.c:
/usr/x86_64-w64-mingw32/sys-root/mingw/include/winsock2.h:15:2: warning: #warning Please include winsock2.h before windows.h [-Wcpp]
And with this patch we dutifully obey.

include/qemu/sockets.h also has windows.h included before winsock2.h
Presumably it didn't cause a failure for you because everything using
sockets.h already pulls in osdep.h. A reason to prune sockets.h
headers perhaps.

Daniel

More generally we could prune anything including windows.h manually
(there are a dozen or so .c and .h files doing that currently).
thanks

I honestly do not have time to work on this. :(

That's OK, I currently have a bunch of include file cleanups
going through so one more won't hurt too much :-)

Without that patch, windows.h will include winsock.h
(which conflicts with winsock2.h) when compiling sdl.c.
Normally we define WIN32_LEAN_AND_MEAN, and
windows.h won't include winsock.h.
include/ui/sdl2.h and ui/sdl.c undefine that macro,
so the order of the include files is important.
Without testing this, I think that Paolo's patch is needed
since commit e16f4c8770b73f530dad842a31298963b6c7e41d.

That also explains why only that file complains. Thanks!

Applied to -trivial, adding Stefan's comments to the commit
message too.
