Thanks!

I looked at mbedTLS (formerly PolarSSL) before I even embarked on it based
on other recommendations, but it claims to require c99:

Have you had success building it on other systems? What compilers could you
get away with? I'd rather not reinvent the wheel but it seemed like I had to.

Didn't lsh get some updates? Or was I thinking of something else? ISTR that
MacSSH used lsh under the hood.
