New Error Message from FMDatabaseAdditions.m

I have just started receiving the following error message when I compile my Ipad app: FMDatabase method definition for 'applicationIDString' not found. (Same error message for setApplicationIDString).

When inspecting FMDatabaseAdditions.m I see that these methods are being called within an #if construct:

#if TARGET_OS_MAC && !TARGET_OS_IPHONE

I have not changed anything about my targets recently (That I know of!) If you know anything about this error message, your help will be appreciated.

Thanks, Steve
