when I compile my application, I'm getting a lot of:

After searching for a while, I found this as a section of curlbuild.h
in generated build/ folder
#defineCURL_PULL_WS2TCPIP_H1
#ifdefCURL_PULL_WS2TCPIP_H
#ifndefWIN32_LEAN_AND_MEAN
#defineWIN32_LEAN_AND_MEAN1
#endif
#include<windows.h>
#include<winsock2.h>
#include<ws2tcpip.h>
#endif
However, even if I switch position of windows.h & winsock2.h, the
problem won't go away. I'm wondering it may be due to another
declaration of winsock2.h in my application, or I do anything wrong
with the configuration?
The reason why the problem isn't going away when you switch is because
when WIN32_LEAN_AND_MEAN is defined then windows.h doesn't include
winsock.h, so it doesn't really matter which order they're in there. My
guess is before including curl/curl.h you included windows.h or
something else that includes winsock.h so when curl includes winsock2.h
it gives you the warning. As far as I know we're only including those
headers socklen_t. If you want to get rid of the warning you'll have to
include winsock2.h before any other include that may pull in winsock.h.
There's probably a better solution but at the moment I can't think of
anything.
