Just a sanity check: was Foundation.framework removed from your target/xcodeproj?

I've had a project that I haven't worked on for a bit that I tried to compile under a more modern Xcode and now I'm getting compile errors in the Pre Compiled Headers saying that NSData is an unknown data type in the headers.
I've tried changing the compiler to each of the supported compilers, changing the target to 10.7, 10.6 and 10.5 but still no joy.

Has anybody encountered this before? or better still fixed it?

I've seed some stuff on Google search about this happening in iOS Apps and a newer version of Xcode fixed it but I've now tried 3.1.4 (on 10.5.8), 3.2.6 and 4.3.2 (on 10.7)

The error is: 

on Xcode 3.2.6

/Developer-old/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/CoreData.framework/Headers/NSPropertyDescription.h:24:0 Expected specifier-qualifier-list before 'NSData' in /Developer-old/SDKs/MacOSX10.6.sdk/System/Library/Frameworks/CoreData.framework/Headers/NSPropertyDescription.h

on Xcode 4.3.2
