The errors I see are:

4 warnings and 6 errors generated.

They appear to be because it is directly accessing ivars that are not public 
and not exposed from a category on GSMimeDocument (in the first instance, I've 
not checked the subsequent ones).  If these ivars are expected to be used 
outside of the GNUstep Base Framework, then they should not be hidden.  If they 
are not expected to be used outside of the GNUstep Base Framework, then the 
Performance framework has a bug that only shows up with the non-fragile ABI.

It fails after the first file, so I've not see what subsequent errors appear.
