It has been different in the past, although with a different menu API.
Now checking for the target platform is probably the best solution.
Given that GetAppleMenu is always available I'd recommend doing:
if (ZCONFIG(OS, MacOS7) || ZCONFIG(OS, Carbon)))
rather than
#if (ZCONFIG(OS, MacOS7) || ZCONFIG(OS, Carbon)))
so that the code is compiled-but-stripped rather than simply ignored,
helping to ensure the code always compiles regardless of which platform
you're happening to test against.
Another possibility would be to use ZApp::HasGlobalMenuBar(), which
returns true only on MacOS.
A+
