[Bug objc/27377] [4.1/4.2 Regression] false compiler warnings generated in Objective-C code

[pinskia at gcc dot gnu dot org]

------- Comment #2 from pinskia at gcc dot gnu dot org  2006-05-05 08:01 -------
Confirmed, reduced testcase:
#include <objc/Object.h>
@interface NSObject
-lock;
@end
static NSObject *local_lock = (id)0;
void GSSetupEncodingTable(id t)
{
 [(local_lock != (id)0 ? local_lock : t) lock];
}


----
For 4.0 and above you can remove the include. And this happens with the next
runtime also.
