The problem is the OCUnit needs the Mac OS X deployment target in the 
build settings to be set to X.3, otherwise I get the compiler message:
`-fobjc-exceptions' ignored because MACOSX_DEPLOYMENT_TARGET is "10.2"
It works fine for now, but may not behave properly if a method throws 
an exception.

Now, there is one thing I don't understand very well the differences 
between the two following settings:
* Cross-Develop using Target SDK in the project General settings
* Mac OS X deployment target in the build settings of individual targets

Maybe the first is only for the headers used by the compiler and the 
headers, and the second is for the linking.

In fact, the way it is setup now, the SDK may not even be taken into 
account, according to Apple's documentation, because we are using a 
non-native target. This is the warning that you should be able to see 
on this file on your computer (Apple's doc):
file:///Developer/Applications/Xcode.app/Contents/Resources/English.lproj/Xcode_Help/Building/chapter_6_section_10.html

So, we think we are using the 10.2.8 SDK but we are probably not if 
our machines are on 10.3!! So updating to a native target seems in 
fact necessary if we want to use the 10.2.8 SDK.

Anyway, if we want to have different targets compatible with 
different OS X versions, we have to find a way to do it. It seems the 
prefix header is where the action is. I will try to read more about 
this.
