Exactly right.  Class property metadata and property metadata for properties 
declared in categories work only with -fobjc-runtime=gnustep-2.0 (or, in 
theory, later), instance property metadata on properties declared in classes 
works only with -fobjc-runtime=gnustep-1.something (I forget which, with 1.7 or 
later we get better metadata)

Methods synthesised from properties should work with any runtime.
