curl exit code 60 on Windows

Many times the curl tool version available to you on windows is outdated and doesn't ship with up to date ca certs. A workaround for this is to grab the latest cacert.pem from curl here in the same location as curl, and rename it to curl-ca-bundle.crt. Thanks to Cheeso for the solution. I ran into this while trying to use emacs-request on windows.
