For the five minutes necessary to verify this, my mac mini has heroically
killed its harddrive. Have my SO's mac now but it doesn't have a compiler
on it and I'm tired.

I think what we want is below, but I probably have some cheesy semantics wrong.

If someone has a MAC with a compiler you can verify this in a cinch:
after:
# define IOV_MAX 1024
add:
#error "DEFINED IOV_MAX!"
... and try to compile. It'll die if you have OS X panther or lower.
If you have OS X tiger or higher, switch the <= to >= and add the #error define
just to be sure it's working.

Extra details, so anyone can jump in and say yay or nay :P I verified build
and test under linux with this patch for shiggles.

Unfortunately, I'm tired and must give up for the night. Weekend was much
more eventful than anticipated. Tomorrow I must procure putty knives.
