Some very recent commit broke building on Tiger PPC

The build made it to here:

I haven't tested on Leopard yet; will wait until this is fixed first since it seems likely to break in the same place on Leopard too.

Could you try #92?

Travis CI supports VMs for older SDK versions, but only down to OS X 10.9 (afaik). I wonder if there is some other service or some other way for us to more easily test whether or not we're still building on older SDKs than making @chdiza suffer through it every time?

It's not too big a deal. Changes to src/macvim or other Mac-specific tweaks are usually spaced far apart enough that I'm not glued to by Powerbook G4 doing testing.

Good news. This patch fixes building on Tiger PPC. Also, with this patch applied, Leopard PPC builds and passes the "will it open up and go in and out of fullscreen" test.

Thanks, @splhack!
