Well, there were some endianness functions and #includes fixes too, and
I'm all for getting rid of local patches. :)

Damon: in the meantime I would build mosh from git.  If you can't, use
the following port that *might* be ok for OpenBSD 5.3 (you have to
unpack it in /usr/port/mystuff, so that you get
a /usr/ports/mystuff/net/mosh directory).

Also OpenBSD 5.4 is around the corner and will ship with a working mosh
package -- unless you run some ARM flavor, but that's another mail
for mosh-devel.
