How could you not use a bunch of #ifs if the code actually uses 10.7+ API calls 
that have to be filtered out?

Well, there *is* a way to do it following Qt's approach with d-pointers, where 
you put new stuff and things that don't work across the board in a private 
class, but that only reduces the number of #ifs required for features that 
aren't available on all supported platforms. And it's (probably) trickier to do 
right in C than C++ (as far as that's relevant here). Of course it also requires 
a far more extensive refactoring effort than simply putting #ifs all over the 
place.

And such an effort and extensive changes would probably be deemed out of 
proportion upstream if they're only to support a legacy OS, unless you can make 
a case that it'll prove useful for future introduction of other features that 
require a newer SDK than they'd like to require.
