Fair enough.  The alternative is to surround lines 1211-1213 in packet.c
(the only place in the codebase where TCP_NODELAY is actually used) w/ a
simple #ifdef TCP_NODELAY.  Somehow, I suspect though that libc5 builds of
the Linux kernel still respect 1 as the value for TCP_NODELAY.  Regardless,
our top priority is to make sure the app compiles and works -- and I've been
more concerned than most about SSH's performance.

If it won't compile, it performs pretty terribly :-)
