--- Comment #89 from Julian Waters <tanksherman27 at gmail dot com> --- Understood. I will try to improve the check in that case. A side effect of this is that native TLS will be enabled by default for Windows unless --disable-tls is passed, unless I rewrite the check extensively, which doesn't seem to be desirable. But besides the configure thing, any other objections?
