however, attempts to build it without /--disable-libssh/ result in a linking error:

Oops, sorry, I missed one include. Here is the fixed patch, now it compiles both with and without libSSH.

No, unfortunately it does not - not any more, at least:

Configured with

./configure --disable-libssh

it doesn't compile proto/rpki/ssh_transport.c because it references "struct ssh_sock" and "SK_SSH_CONNECT", whose definitions are excluded in lib/socket.h unless HAVE_LIBSSH is defined →

Again: Thanks for your great support!
