[Qt-interest] Mac deployment to 10.4

[Pavel Koshevoy]

It's not qmake/Qt that allows you to deploy to OSX 10.4 while building 
on OSX 10.5.  It's Xcode and 10.4u SDK.  You can specify 10.4 target 
version in qmake .pro file, and that will build your project for 10.4 
deployment.  However, you will still need to link against Qt, and if you 
don't build Qt against 10.4 SDK you won't be able to link to it (or even 
if it will link it will not run on 10.4).

    Pavel.
