What surprises me is that there aren't any warnings as one does this.
gcc 4.0 is active, and I select a 10.2 deployment target, and the
10.2 SDK -- why do I get a build? why don't I get an alert error
telling me that this just won't work out?
gcc 4 is active, and I select a 10.3 deployment target, and the 10.3
SDK -- why don't I get an alert telling me that this will only run
on 10.3.9 and later?
In each of these cases, I should get the alert noted, including some
pointer to the relevant instructions to resolve the issue -- at least,
if the Xcode team followed the HI guidelines....
Be seeing you,
Ted
