But why is that needed? On lib/config-win32.h line 626, HAVE_STRUCT_POLLFD is
defined if winsock2.h exists so that section you modified would be skipped!

These windows compiler setups are carefully crafted over the years so I really
want to only change them when we fully understand exactly why and how.
