What exactly is wrong with that?

Which header is that prototyped in?  Can we avoid #including it?

Up until yesterday there was an #undef there.  Vodz just removed it.  I don't 
know why.

Actually, that's a good thing to do anyway.  There's no point in wasting 
compile time building libraries we're not going to use.

That said, I don't think losetup is ever going to work on MacOS X.  And lots 
of our applets get data out of /proc, which macos X doesn't have.  At best 
you're only ever going to build a subset.

Does it have the functionality?

We have a #platform.h to hide those kind of differences...

Much as I'm interested in getting busybox to work on MacOS X, it's going to 
take me a little while to work through a patch this big doing this many 
different things...
