There are ssh-1.2.33 binaries for QNX4, the main feature is the fact they are linked with the current zlib v1.2.1 and gmp v4.1.4 (QNX security patch and tcptk50.tar.F were used as well).
Moving from gmp v2.0.2 to v4.1.4 gave a performance boost one will surely notice. ssh-keygen works twice as fast…
