ray/thirdparty/patches/prometheus-windows-pollfd.patch

Target an older version of Windows SDK so that we don't get a conflicting definition of struct pollfd

Windows Vista and later SDKs define struct pollfd for WSAPoll(), but it has a permanent bug:
- https://curl.haxx.se/mail/lib-2012-08/0014.html
- https://curl.haxx.se/mail/lib-2012-10/0038.html
civetweb provides its own implementation of poll, but it has a conflicting definition for pollfd.
Hence we block Windows from defining pollfd (which this project doesn't use).
