Details:

I'm getting the following when compiling gnustep-base in GC mode:

Making all for library libgnustep-base...
 Compiling file NSObject.m ...
NSObject.m:703:29: error: incomplete definition of type 'struct objc_class'
  gc_type = (GC_descr)aClass->gc_object_type;
                      ~~~~~~^
/GNUstep/Local/Library/Headers/objc/runtime.h:68:16: note: forward declaration
of 'struct objc_class'
typedef struct objc_class *Class;
               ^
1 error generated.


I'm using libobjc2 trunk (with boehm_gc=yes) and base trunk. 

I configured make with:
CC=clang ./configure --with-layout=gnustep --prefix=/GNUstep
--enable-debug-by-default --enable-objc-garbage-collection 

I'm not sure how to fix this myself.
