which Rust version

[bAndie91]

Hi, which Rust version have you managed to compile with?
i've tried 1.2.0-i686-unknown-linux-gnu (1.2.0 (082e47636 2015-08-03) was the latest at your last commit) and 1.40.0 (73528e339 2019-12-16) too.

1.40 compiles but produces runtime fault:

LD_PRELOAD=$PWD/libsrvshim.so nc -v _autodiscover._tcp.dreamhost.com 443

thread '<unnamed>' panicked at 'called `Option::unwrap()` on a `None` value', src/libcore/option.rs:378:21
