   Without verification by looking at the sources, I think you've run
into a change in the typedef for `Class' between gcc 2.6.3 and gcc
2.7.0.  The change was made to make gcc conformant with the NeXTSTEP
implementation.  

   Trying compiling the Objective-C runtime that comes with gcc 2.7
with gcc 2.7 and you shouldn't have any problems of this type.
