It is impossible to fix it in GNUstep Base, because we can’t guarantee that
user code doesn’t include system headers after including GNUstep headers (not
to mention the fact that GNUstep is not the only Objective-C standard library
implementation out there). If the user does, for example:
#import <Foundation/Foundation.h>
#include <something_that_includes_cdefs.h>
void example()
{
__weak id foo = bar();
baz(foo);
}
Then they will get a compile error no matter what GNUstep’s Foundation.h does.
It can’t prevent cdefs.h from redefining __weak to be something different.
I’ve just looked at the GNUstep base changelog since that NetBSD commit and
there are no relevant changes, so I’ve no idea what the NetBSD people are
thinking there.
