Gestalt() is a good approach, but never use gestaltSystemVersion. See
Gestalt.h for why.
I don't think you need to never use it. Its failure mode is fairly
benign and completely documented. If you're only interested in
checking for numbers under 9, such as in this case, then it works just
fine.
Well, true enough, but I think my recommendation is still a good idea,
for reasons of style and maintainability. Someday someone else may need
to change that code. If one day 10.5.11 is required the codechange is
less straightforward and more error prone.

Re: How do you get the OS X version number in C or C++?
gestaltSystemVersion is not the best way to do it (and it caused
problems in 10.4.10 and up).
As the documentation in Gestalt.h states:
... A better way to get version information on Mac OS X would be to
use the new gestaltSystemVersionMajor, gestaltSystemVersionMinor, and
gestaltSystemVersionBugFix selectors...

What framework do I include in my Xcode project to pull in Gestalt? I've
tries CoreServices, Carbon and Cocoa.

I'm an idiot! I was trying to include gestalt.h directly.

I don't think you need to never use it. Its failure mode is fairly
benign and completely documented. If you're only interested in
checking for numbers under 9, such as in this case, then it works just
