commit a10d8552d0d2438da4ed539275abcbf557d1e7a8
Author: Darren Tucker <dtucker at dtucker.net>
Date:   Tue Feb 27 14:45:17 2018 +1100

    Conditionally compile XMSS code.
    
    The XMSS code is currently experimental and, unlike the rest of OpenSSH
    cannot currently be compiled with a c89 compiler.
