First, please don’t expect the sizes for different runtimes to be the same (or, necessarily, to be even very close).  The Mac runtimes have a bit more support from the linker for various things.  To ensure that property introspection is consistent without this support, the GNUstep runtime IR generation emits property definitions in all compilation units and then uniques them later.

We’re currently working on a new ABI for the GNUstep runtime that should address the size issues, but until then this looks pretty much what I’d expect.
